Who would have thought so many people had a deep emotional investment in Venus being a blur circle ;-) Seriously though, maybe people need a demonstration of focus on a non-controversial small light here on Earth to convince them.
It is obvious that there are a lot of people that don’t understand how cameras work but a lot of these same people will try to tell us that the professional and amateur astronomers don’t know what they are doing!
I did; it was on maximum zoom at the end. The reason it looks so big to start with is because it is out of focus, and all you're seeing is the bokeh... en.wikipedia.org/wiki/Bokeh cdn-7.nikon-cdn.com/Images/Learn-Explore/Photography-Techniques/2012/Bokeh-for-Beginners/Media/Lindsay-Silverman-Bokeh-lights.jpg
Boke (Japanese) means 'blur'. Should that have influence on the size? The image seems to have a well defined edge before adjusting. Boke (Urdu) = boats and boke (Chinese) = blog btw.
Out of focus light sources (Bokeh) are shaped like the lens aperture, not the shape of the light source. As the image is focused more and more, the light source gradually changes into its true shape. Here's a demonstration I just filmed, using a crescent shaped hole cut in a piece of paper... ua-cam.com/video/M5iwgk1-bkU/v-deo.html
Ok so here is my question - is every single person on youtube just not very smart? Cuz even people that are not "flat earthers" have videos out there of stars growing, shrinking, darting around quickly, changing shape, I have probably literally (and I mean that word) 1000 some videos on here, and yours is the *only* one I have seen that looks like this - I don't have 600 dollars to buy my own or a friend with one, but I don't understand how 999 times out of 1000 they don't look like this.
Most people think that because the camera can auto-focus perfectly well in the day time, it will also auto-focus perfectly well at night. Unfortunately pretty much all cameras have trouble auto-focusing on tiny, light sources at night when most of the frame is black, and unless people realise this and focus the camera manually, their footage is going to be out of focus.
Quantum change flat earth Rev 12 Is 66, you saw how Venus was focused into a distinct object in front of yours eyes. Did you think that was a trick? Also, the correctly focused image in this video looks similar to what's seen in a telescope further suggesting that the initial image was out of focus, and not what it actually looks like.
I came here to look at how to set up a shot for jumpier and its moons. It kept auto focusing and being blurry but if I held the button it would autofocus but then the wiggle of the camera would make the shot have streaks. Get a 300 dollar Orion telescope and look at the moons of Jupiter. It’s life changing! :D the rings of Saturn kind of just look like a smudge but still pretty neat.
Folks should take note of what the blur circle looks like. It's grainy and has concentric circles. If someone tries to convince you that that's what a planet or star looks like in some other video, don't believe it. I really like your graphics on the right side with the command wheel. You even got it to rotate, which must have taken some time. Some tips that may be helpful - I find the command wheel difficult to use. You can reassign the W/T adjustment on the left side of the lens to manual focus since it's redundant as is. Hit the menu button, go to settings, and go to "Assign side zoom control" and change it to "MF" for manual focus. In manual focus mode if you press on the right side of the command wheel it sets the focus to what the camera thinks it should be. Usually this gets you close to the correct focus, so it saves time. Manual mode may be the best way of doing it, but it's a confusing mode because if you're not careful some setting will persist from the last time the camera was used. I wonder how good you could do with auto mode, but setting the focus to the mountain icon indicating distant objects (it does not have manual focus) combined the exposure compensation. Maybe if you zoom in it will help it get the focus right, and then you can pan out. I haven't tried this though. I've had a lot of rain here in Austin, but once it clears up I'll be taking more photos of the sky with my P900.
Most of them might not understand the experience and creativity you've used in this video.... But it's awesome way to control the exposure ... This is one of those videos , i don't know how to search for... Thank you vertigo.... Love this❤️
Bro please I need your help, i have a problem with my new camera since some days, my nikon p900, when I put it in manual mode, and I try to take a picture, the pictures is completely white, if I record videos in manual mode, or I take pictures in others modes, they are ok, but when I take pictures with manual mode, the pictures is white, I don't know how to solve this, please help bro!
Hi, this is really helpful. Trying to figure out where you jump to after 1:53 - do you switch to back REC mode when you shine the light on the lens? I noticed the AE-L option only shows up in REC mode (and not in M mode) Just trying to figure out where you jump to after 1:53. thanks!
Bright things that are out of focus produce a blurred shape (Called Bokeh) that is much larger than the object is when it's in focus. Here's another example where I show the same thing happening with a plane's lights... ua-cam.com/video/6sncmX0mNqM/v-deo.html
My P900 doesn't seem to have manual focus in manual mode or movie mode! I only get manual focus in the U or user setting, and in most of the 'special effects' settings. I can switch focus to infinity though.
How strange. Not sure why you wouldn't have that feature. Also be careful with the infinity focus setting too; there are two different "infinity" modes. One has an icon that looks like mountains, the other has an infinity symbol (∞). Only the infinity symbol mode actually focuses to infinity. The other one only stops the camera focusing close to you.
how are you keeping venus framed in the center like that while focusing?..... also one wrong button on the P900 in the dark and you have to go through that whole thing again.... it goes back to center focus.... that camera is a pain in the arse!
The tripod is stationary, so it's not staying in the centre at all. If you notice, it's drifting to the bottom right of the frame as I focus it. And yeah, I know that you mean about the controls. The P900 isn't really designed to do manual work! Hopefully if they release a successor it will be more manual friendly! :)
Thank you, Movie Vertigo, for this tutorial, which makes things very clear, at least to those who are willing and able to understand how to handle cameras and camera lenses. To make things even clearer, I would like to point out, that the correct focus at any given focal lenght is always there, where the source of light gets displayed AS SMALL AS POSSIBLE. Here - and nowhere else - is the focal point of any optical lens. This spot must be exactly there, where the imaging sensor of your camera is located. Is it located somewhere behind or somwhere before the sensor, you will obtain only a blown up blob of light. And, by the way, tiny turbulences of the air inside the camera, caused by thermic gradients, will make those blobs wobble and twinkle. I'm doing astrophotography for many years now, and I know very well what painstakingly precise focussing requires and how crucial it is.
Thanks for the tutorial. I do have one question though. How is it possible that we can see Venus in the night sky if it's the 2nd planet from the sun? Venus and Mercury should not be visible from the "night side" of earth ;-)
Movie Vertigo thank you. So,’with this diagram we should only see Venus during the very early morning in the eastern horizon or during the sunset looking towards the western horizon and only for a few minutes at that. I’ve seen Venus several times during the late nights and at about 45 degrees above my horizon looking west (I live in Southern California, Los Angeles to be exact). I took astronomy for two years in college and have viewed Venus from he Griffith observatory as part of a project and it was about 8-10 pm and the planet was directly above our heads. But, let’s just say the diagram you sent is valid... please explain how we can see Mercury above our heads in the nights sky? BTW, I tally appreciate your response. Thank you for taking time.
Venus can be up to 47 degrees away from the sun (See en.wikipedia.org/wiki/Elongation_(astronomy) ), so your observation of 45 degrees above the horizon fits within expected limits. Mercury has a lower maximum elongation of 28 degrees, so you will never see it above 28 degrees above the horizon "at night". Can you provide me with the date and time of your observation at the Griffith observatory? Venus will never be overhead at night, so perhaps it was a different planet. If I know the date and time, I can use the Stellarium application to find out what your night sky would have looked like from that position.
Hi, I tried your technique with some success with Jupiter. I have some questions though. What ISO do you use when filming the stars? Also is your technique applied while in Movie mode? I ask because if I'm in the still picture mode when I push the ring to the right to fix the exposure a red light illuminates on the front of the camera, but when in Movie mode I get the AE-On option. Lastly a couple of my attempts resulted in Jupiter disappearing completely, I guess this means under exposure? Cheers.
This technique is for movie mode. If you're taking still images you have full control over the exposure as you can change the shutter speed, ISO and aperture. I haven't really tried any star photography with the camera yet, so can't answer your question about ISO. If Jupiter vanishes when it should be in shot, then yes, it's probably under exposed.
I used my phone. Just keep aiming it further and further away from the lens (And by this, I don't mean moving it a further distance away. I mean rotating it so it's facing off to the side of the lens). Eventually it *will* be dark enough as it won't be pointing at the lens.
@@BackToTheCovenant Yes. Normally when taking video, the camera is constantly adjusting the exposure based on the light level. AE-L locks the exposure at the current level.
I didn't for this tutorial video, no. I didn't actually have one at the time. I do have a solar filter now, though I'm not sure if it would be any use in this situation. I might give it a when Venus is visible in the evening again next year.
Thank you for the video! I didn't understand the moment you switch from M mode to Video mode after adjusting focus and exposure. Could you explain? Thank you very much!
The same focusing and exposure technique will work with anything the camera is having trouble focusing on. I haven't used the time lapse mode myself, so I don't know much about it.
Thanks very much.I caught Aldebaran going behind the moon last night on a time lapse.I wasn't expecting it but when watching my video I wasn't sure which star it was but found out today it was Aldebaran in the Taurus constellation.I'll be using this trick hopefully tonight.
Hmm when I press that multiselector ring it take me to exposure compensation, it does not lock the exposure. And in full manual mode it change my focus. it don't lock. I'm doing somethign wrong.Ohh damn that function is only avaliable when recording a video. :(
Photography with a telescope (instead of telephoto lens) presents more or less the same difficulties. However, there is equipment far more appropriate for astrophotography than the p900.
Indeed, a telescope is a much more appropriate tool for the job, but you can get some pretty good results (Considering its cheep price) from the P900 if you know how to use it. I made this video because of all the people trying to use auto-focus on stars and planets and wondering why they got the result they did!
+Heed the Seen The 83x is more of a marketing number. It doesn't tell you anything about the maximum magnification, just the ratio between the mimimum and maximum magnification. The focal length is what really tells you how much magnification you're getting.
, can you do this video again but in one clear shot please., i'd like to see the moment that the 'circle' becomes a slight 'crescent'., in this video the shape of the image changes twice., on the first occasion it has cut from one view to another, and on the second occasion it changed during the torch being shone at the camera., it would clear things up if you could do it in one continuous shot., thanks.,
The moment that the over exposed Venus (which looks like a circle because of glare) is correctly exposed to reveal the crescent *IS* one shot. The torch is shone in to the lens like that because the P900 (with the current firmware) has no manual exposure control in video mode. If they ever release a firmware update to the camera that addresses this limitation, I'll be sure to produce a new video showing the exposure transition without the torch.
+Robert Greenfield Indeed. But I do try and politely explain their mistakes. Hopefully it'll get through to some of them, and show them how they can test these things for themselves... ua-cam.com/video/M5iwgk1-bkU/v-deo.html
@ Kim Granger:The visual shape of Venus depends on its (or is it "her"?) position related to the sun. Of course Venus is a nearly perfect globe, a "spheroid". On its ("her"?) orbit around the sun, the sunlight meets Venus from different directions, so Venus shows us changing phases, like the moon. With one difference, which is nice to observe: Venus has an atmosphere with dense clouds, which disperse the sunlight. So, the reflection of sunlight along the planet's boundary sometimes seems to reach over more than one half of the visible disc - a view which the moon would never allow.
Quick question, after correcting exposure you say you can fine tune the focus. Won't that mean I'll lose the exposure again? Excellent vid. I'm new to photography and this is the most helpful vidx I've found so far.
The focusing part works the same for photos. The exposure part isn't necessary as you can manually set the shutter speed to achieve the correct exposure when taking stills.
Unfortunately the P900 has very limited exposure control in video mode. For still photos you have full manual control, but when recording video you cannot directly control the exposure. All you can do is "lock" the exposure at it's current setting, which is why you have to resort to this light-in-the-lens method. Hopefully the P1000 (being released in September 2018) will have better exposure control.
did you have the zoom maxed out when doing this shot? and what are the other settings l need to dial in to get this shot.thankyou so much for explaining how to use this great camera.cheers.
Why do all the "out of focus" stars look different? Shouldnt they look the same? Why are some rainbow coloured? Why are some yellow? Why are some white and black? Its endless.
No, they won't look the same. There are many factors involved, including amount of atmospheric turbulence, humidity, angle of star above the horizon, colour of star, type of camera used, how much out of focus it is, to name but a few.
How come no one can show me a video of a star focused "correctly"? I only see people showing venus. The only videos of stars I see are the "out of focus" p900 videos.
Stars are so far away that they appear to be point light sources for cameras/telescopes on earth, and zooming into a star won't reveal any more detail as it will still be the size of a single pixel (assuming it's exposed correctly), so there's nothing interesting to be seen focusing on a single star. Therefore most correctly focused photos of the stars will be wide angle shots to show the constellations and positions of the stars relative to each other.
Thanks for this simple but great tutorial!! I have just purchased the P1000 and have some great shots of the moon. I am keen to see Jupiter and Saturn and maybe the Orion Nebula. One question - does it have to be in movie mode or can you do it as a still?
All of those can be taken as stills. In fact with the P900, it's easier to do stills than video as you get better exposure control. They finally added manual movie exposure control on the P1000.
That can take quite a bit of trial and error to learn. If it's underexposed, basically it will be too dark. If it's just a little underexposed that can be corrected by brightening up the video later. But if it's too underexposed, when you brighten it up, the footage will be too noisy, or the details will be lost to the compression artifacts.
I'm sure many (most?) of them know fine well it isn't in focus, but the blurry, shimmery balls they're showing gives them an excuse to shout about NASA and science being "lierz!".
Anthony Rodemus They think there are "waters above the dome" so if their image looks like it's distorted & shimmering due to flowing waters they assume that's the correct & best view of the object, never mind all the controls available on the camera: those were just put there by NASA to confuse people.
Thanks for the info, will give it a try. I love my P900 but pretty disappointed that Nikon didn't give the camera unlimited flexibility in manual mode. Likely technical reasons why but still disappointing.
The manual focus works for pictures. The light technique isn't necessary though as you can manual control the shutter speed and therefore the exposure when taking still images.
Movie Vertigo i was trying to take a close up picture of some stars last Night and they end up looking blurry like your comparison pictures and I don't know what I was really doing wrong so you're saying I need to put it in manual mode to be able to get them to come out clearly? Sorry this is my first camera...literally got it a week ago and trying to feel my way around
The P900 has trouble focusing on small light sources at night (e.g. stars & planets) so you have to manually focus in this situation, yes. Larger sources such as the moon, it can focus on fine in auto mode.
Great video! And flat-Earthers film Venus and try to tell us that it isn't a planet all because they can't figure out how their camera works. It's unbelievable! I've always figured it was some focus issue, because I've seen Venus countless times through my telescope and it looks nothing like the weird camera shots. It looks like an actual crescent like this.
Great detailed instruction. Don't worry about the negative comments because the probably don't even own a camera when I get mine I will try this. It seems that most of the problems with this camera is the operator .
I replicated your settings before hitting record and then again while i was recording (introduced the light both before and during) but neither instances produced a clear image of Jupiter. I'm stuck with a white blob of light or the funky glowing/pulsing cell.
AE-Locked and adjusted focus, but once the image was clear it was a tiny Jupiter. Jupiter has been the brightest I've ever seen this past month but how close is it cuz your other video had a huge image of Jupiter.
Does shining a light into the lens work for taking still images as well? I got a good shot of Jupiter and 4 moons last night but it is overexposed and looks like a white ball. I was using the "moon" setting and tried using negative exposure compensation but it didn't do much good.
@@yoichifranck3753 It does have a long(ish) exposure at ISO 100 of 15 seconds, but this gradually reduces as the ISO is increased. At maximum ISO, the maximum exposure is 1/2 second. If you want to do long exposure photography, I'd recommend a proper DSLR/Mirrorless camera.
Thank you for this. I had the focus Down, but didnt know how to fix the exposure problems i ran into when filming Jupiter and Venus. Will try the external light source NeXT time, Thanks
No. It has phases, just like the moon, where you're seeing both the illuminated side and the dark side. More info here... en.wikipedia.org/wiki/Phases_of_Venus
Most modern lenses can focus beyond infinity, so just setting maximum focus doesn't work, and the P900 doesn't seem to have an easy way of finding the infinity position.
Watch this video and see the same effect happening with plane lights. See how the light is spread out when unfocused, and small when focused... ua-cam.com/video/6sncmX0mNqM/v-deo.html
nice tips! I knew how to focus it, but didn't know you could use light to lock the exposure, going to try that, thanks! I unfortunately just posted my over exposed Venus video minutes before finding this.. lol! Guess I'm going to have to re-do it!
Flat Earth Talk Strange that you're here, considering that flat earthers love to use out of focus pictures of Venus to show it "isn't a planet" but a "luminary".
Thank you so much for making this so simple! Im a new photographer and just got my P900! Im overwhelmed at the functionality. Its pretty simple to operate but, I just needed clear instruction on how to zoom. Thank u and I subbed! ❤️😘
Note: Not mentioned in the video itself is that at 1:54 I press record to go into video mode.
Depressing that this simple clear tutorial gets so many dislikes - shooting the messenger rather than thinking about the message.
I know, right!
Lappan Sommer
People who are wedded to a faith, don't want to know the message.
Who would have thought so many people had a deep emotional investment in Venus being a blur circle ;-)
Seriously though, maybe people need a demonstration of focus on a non-controversial small light here on Earth to convince them.
Maybe like this one? :)
ua-cam.com/video/M5iwgk1-bkU/v-deo.html
@Noor Gymnastics there is a pause option on yt videos. I highly recommend it.
It is obvious that there are a lot of people that don’t understand how cameras work but a lot of these same people will try to tell us that the professional and amateur astronomers don’t know what they are doing!
👍
why didn't you zoom in as much after you fixed it?
I did; it was on maximum zoom at the end. The reason it looks so big to start with is because it is out of focus, and all you're seeing is the bokeh...
en.wikipedia.org/wiki/Bokeh
cdn-7.nikon-cdn.com/Images/Learn-Explore/Photography-Techniques/2012/Bokeh-for-Beginners/Media/Lindsay-Silverman-Bokeh-lights.jpg
Boke (Japanese) means 'blur'.
Should that have influence on the size? The image seems to have a well defined edge before adjusting.
Boke (Urdu) = boats and boke (Chinese) = blog btw.
It's from the Japanese and refers to the blur, and yes, as the image is unfocused it blurs and spreads out, changing its size.
Now I still wonder about the change of shape. The well defined edge of the blurred object. But in time the answer will come. I always trust in that :)
Out of focus light sources (Bokeh) are shaped like the lens aperture, not the shape of the light source. As the image is focused more and more, the light source gradually changes into its true shape. Here's a demonstration I just filmed, using a crescent shaped hole cut in a piece of paper... ua-cam.com/video/M5iwgk1-bkU/v-deo.html

Thank you vertigo.... Love this❤️
At this point, if you're going to be doing astrophotography a lot, you might just want to get equatorial telescope instead.
Yes, that is the eventual plan, when budget allows!
The music in the video was soothing! thank you !
Bro please I need your help, i have a problem with my new camera since some days, my nikon p900, when I put it in manual mode, and I try to take a picture, the pictures is completely white, if I record videos in manual mode, or I take pictures in others modes, they are ok, but when I take pictures with manual mode, the pictures is white, I don't know how to solve this, please help bro!
In manual mode you have to make sure the exposure is correct yourself, the camera doesn't do it for you. Try reducing the shutter time.
Ok I'll try, thanks so much bro for thanks for answering!
OMG thanks..... its the same with other planets?
Yes, the same method for focusing on any of the planets or stars.
At 2:10 I cannot figure out how to get it to say AE-L at the top. Am I doing something wrong? I am pressing right on the circle button as it says
There's a slight gap in the tutorial . Make sure you start recording video before that step.
Hi, this is really helpful. Trying to figure out where you jump to after 1:53 - do you switch to back REC mode when you shine the light on the lens? I noticed the AE-L option only shows up in REC mode (and not in M mode) Just trying to figure out where you jump to after 1:53. thanks!
Ah, this isn't too clear is it. Yes, the light shining trick is for when you have swapped into video recording mode.
thanks!
What I don’t understand is why the star looks so different before and after focus it makes no sense
Bright things that are out of focus produce a blurred shape (Called Bokeh) that is much larger than the object is when it's in focus. Here's another example where I show the same thing happening with a plane's lights... ua-cam.com/video/6sncmX0mNqM/v-deo.html
will this work for stars too ?
Yes, you can focus on stars using the same technique, though stars aren't as bright as Venus, so you shouldn't need to adjust the exposure.
Movie Vertigo thank you, i will give it a go :-)
My P900 doesn't seem to have manual focus in manual mode or movie mode! I only get manual focus in the U or user setting, and in most of the 'special effects' settings. I can switch focus to infinity though.
How strange. Not sure why you wouldn't have that feature. Also be careful with the infinity focus setting too; there are two different "infinity" modes. One has an icon that looks like mountains, the other has an infinity symbol (∞). Only the infinity symbol mode actually focuses to infinity. The other one only stops the camera focusing close to you.
I only found the ∞ infinity focusing mode after having made this tutorial. At some point I hope to make a new tutorial showing off this feature.
It is strange. I'm going to have to go right through the manual again!
I have noticed the mountain symbol for infinity does not focus on planets. Except the moon!
The camera can focus on the moon without any issues as it fills enough of the frame for the auto-focus to have something to lock on to.
Did you take this with a Nikon coolpix p900
Yes
how are you keeping venus framed in the center like that while focusing?..... also one wrong button on the P900 in the dark and you have to go through that whole thing again.... it goes back to center focus.... that camera is a pain in the arse!

Movie Vertigo do you have any idea of when they are going release the successor?
No idea I'm afraid!
Hi, I'm from the future and the release date was 6 September 2018
😄
Does this work for Mars or Saturn?
Yes
Thank you, Movie Vertigo, for this tutorial, which makes things very clear, at least to those who are willing and able to understand how to handle cameras and camera lenses.

I ask because if I'm in the still picture mode when I push the ring to the right to fix the exposure a red light illuminates on the front of the camera, but when in Movie mode I get the AE-On option. Lastly a couple of my attempts resulted in Jupiter disappearing completely, I guess this means under exposure? Cheers.
This technique is for movie mode. If you're taking still images you have full control over the exposure as you can change the shutter speed, ISO and aperture. I haven't really tried any star photography with the camera yet, so can't answer your question about ISO. If Jupiter vanishes when it should be in shot, then yes, it's probably under exposed.
Hi! Great video! Which light source do u use? My phone is too bright. Thx!
If it's too bright, just point it slightly away from the lens until you get the required light level.
@@MovieVertigo thank u for the quick feedback. I tried it but it didn't help enough.
I would like to know what light source you use. Thanks again!
I used my phone. Just keep aiming it further and further away from the lens (And by this, I don't mean moving it a further distance away. I mean rotating it so it's facing off to the side of the lens). Eventually it *will* be dark enough as it won't be pointing at the lens.
@@MovieVertigo alright, thank u very much for the quick help
I’m not seeing AE-L appear. Doing exactly what you have in the video. Wonder what I’m doing wrong.
Not mentioned in the video itself is that at 1:54 I press record to go into video mode. This might solve your issue.
@@MovieVertigo So what your saying is the AE-L feature can only be activated while taking a video?
@@BackToTheCovenant Yes. Normally when taking video, the camera is constantly adjusting the exposure based on the light level. AE-L locks the exposure at the current level.
@@MovieVertigo Thanks
I have this camera; very interesting. Excellent tutorial.
hello movie vertigo thankyou very much for explaining how to use the p900 properly.Can you do one of Saturn but not in movie mode. thanks?
Saturn will be at it's closest point in the summer. If I remember I'll try and get some still photos then.
thanks lm looking forward to that
Do you use filter?
I didn't for this tutorial video, no. I didn't actually have one at the time. I do have a solar filter now, though I'm not sure if it would be any use in this situation. I might give it a when Venus is visible in the evening again next year.
Thank you for the video! I didn't understand the moment you switch from M mode to Video mode after adjusting focus and exposure. Could you explain? Thank you very much!
Yes, there was a lack of explanation in the video, but I go into video mode (press record) at 1:54
Thank you this will help me a lot.Will this work when in the time lapse mode or on Jupiter and Mars?
The same focusing and exposure technique will work with anything the camera is having trouble focusing on. I haven't used the time lapse mode myself, so I don't know much about it.
Thanks very much.I caught Aldebaran going behind the moon last night on a time lapse.I wasn't expecting it but when watching my video I wasn't sure which star it was but found out today it was Aldebaran in the Taurus constellation.I'll be using this trick hopefully tonight.
Yes I posted your method on my channel thank you.
Yes it will work. The time lapse has an exposure lock feature too
What was the exact time when this footage has been recorded??
It was recorded on 28th January 2017 at around 18:00
Great tutorial! Can i ask the title of the music?
The music is Island Paradise from www.purple-planet.com
Great video, been trying to explain this to people for months!
Nice one well explained
Hmm when I press that multiselector ring it take me to exposure compensation, it does not lock the exposure. And in full manual mode it change my focus. it don't lock. I'm doing somethign wrong.Ohh damn that function is only avaliable when recording a video. :(
Yes, it's not particularly clear in the video, but the exposure lock is only available in video mode.
Another great video. Very well explained.
Hopefully it'll reduce the number of out of focus videos out there!
And this is why, to me, telescopes are better than cameras for seeing reality as it really is
DANG JOS however they can't capture that they seeing
Photography with a telescope (instead of telephoto lens) presents more or less the same difficulties. However, there is equipment far more appropriate for astrophotography than the p900.
Indeed, a telescope is a much more appropriate tool for the job, but you can get some pretty good results (Considering its cheep price) from the P900 if you know how to use it. I made this video because of all the people trying to use auto-focus on stars and planets and wondering why they got the result they did!
Telescopes zoom more.
Nikon P900 zooms up to 83x, optically.
+Heed the Seen The 83x is more of a marketing number. It doesn't tell you anything about the maximum magnification, just the ratio between the mimimum and maximum magnification. The focal length is what really tells you how much magnification you're getting.
Will try this the next time the sky is clear and Venus is visible. I have SO much to learn about this camera.
what kind of light did you use to get the exposure right? like a phone flashlight?
Yes, I used the flashlight on my phone.
, can you do this video again but in one clear shot please., i'd like to see the moment that the 'circle' becomes a slight 'crescent'., in this video the shape of the image changes twice., on the first occasion it has cut from one view to another, and on the second occasion it changed during the torch being shone at the camera., it would clear things up if you could do it in one continuous shot., thanks.,
The moment that the over exposed Venus (which looks like a circle because of glare) is correctly exposed to reveal the crescent *IS* one shot. The torch is shone in to the lens like that because the P900 (with the current firmware) has no manual exposure control in video mode.
If they ever release a firmware update to the camera that addresses this limitation, I'll be sure to produce a new video showing the exposure transition without the torch.
So it is a crescent? amazing what we learn when we go look for ourselves. Thank you. can't wait to try it myself.
FFS, he’s trying to accuse you of faking it. He’s a flat earther.
+Robert Greenfield Indeed. But I do try and politely explain their mistakes. Hopefully it'll get through to some of them, and show them how they can test these things for themselves... ua-cam.com/video/M5iwgk1-bkU/v-deo.html
@ Kim Granger:The visual shape of Venus depends on its (or is it "her"?) position related to the sun. Of course Venus is a nearly perfect globe, a "spheroid". On its ("her"?) orbit around the sun, the sunlight meets Venus from different directions, so Venus shows us changing phases, like the moon. With one difference, which is nice to observe: Venus has an atmosphere with dense clouds, which disperse the sunlight. So, the reflection of sunlight along the planet's boundary sometimes seems to reach over more than one half of the visible disc - a view which the moon would never allow.
Thanks dude been looking for this got into filming planets again so this is perfect!
Quick question, after correcting exposure you say you can fine tune the focus. Won't that mean I'll lose the exposure again?
Excellent vid. I'm new to photography and this is the most helpful vidx I've found so far.
You can continue to focus in video mode by rotating the multi-selector ring, so you won't lose the exposure.
will this method work for photo mode? or only video?
The focusing part works the same for photos. The exposure part isn't necessary as you can manually set the shutter speed to achieve the correct exposure when taking stills.
why you put light inside lens? the camera not have manual diafram?
Unfortunately the P900 has very limited exposure control in video mode. For still photos you have full manual control, but when recording video you cannot directly control the exposure. All you can do is "lock" the exposure at it's current setting, which is why you have to resort to this light-in-the-lens method. Hopefully the P1000 (being released in September 2018) will have better exposure control.
thanks for sharing. can you recommend a tripod?
Not really. I'm just using a cheap one. It isn't ideal because the head movement is really jumpy. Try and get something with a smooth moving head.
mine is jumpy too.
Check out 360 ball tripod heads. Even on my shaky crap tripod the level of control is 100x better with one.
EXACTLY the video I needed. Now I just needs a clear night. Thanks a ton, I was losing my mind trying to figure it out.
You have 9M on the right. I have 0.3M how do I Change that?
This number is affected by the current zoom, I believe.
did you have the zoom maxed out when doing this shot? and what are the other settings l need to dial in to get this shot.thankyou so much for explaining how to use this great camera.cheers.
Yes, the zoom was maxed out. There aren't many settings to play with in video mode. I think everything is described in the video.
thanks
Why do all the "out of focus" stars look different? Shouldnt they look the same? Why are some rainbow coloured? Why are some yellow? Why are some white and black? Its endless.
No, they won't look the same. There are many factors involved, including amount of atmospheric turbulence, humidity, angle of star above the horizon, colour of star, type of camera used, how much out of focus it is, to name but a few.
How come no one can show me a video of a star focused "correctly"? I only see people showing venus. The only videos of stars I see are the "out of focus" p900 videos.
Stars are so far away that they appear to be point light sources for cameras/telescopes on earth, and zooming into a star won't reveal any more detail as it will still be the size of a single pixel (assuming it's exposed correctly), so there's nothing interesting to be seen focusing on a single star. Therefore most correctly focused photos of the stars will be wide angle shots to show the constellations and positions of the stars relative to each other.
You should debunk it using a p900. Show the star out of focus and then change the settings and show the new star. Ive never seen anyone do this.
We finally had a clear night last night, so I went out and captured a star in focus and out of focus... ua-cam.com/video/Fe-b83oajPI/v-deo.html
Thanks for this simple but great tutorial!! I have just purchased the P1000 and have some great shots of the moon. I am keen to see Jupiter and Saturn and maybe the Orion Nebula. One question - does it have to be in movie mode or can you do it as a still?
All of those can be taken as stills. In fact with the P900, it's easier to do stills than video as you get better exposure control. They finally added manual movie exposure control on the P1000.
this already help me a lots.thanks dude!
Glad I could help! :)
Movie Vertigo yes,,i can get the venus clearly now,,
Great video,speaking as a noob,how can i tell if it is Underexposed.
That can take quite a bit of trial and error to learn. If it's underexposed, basically it will be too dark. If it's just a little underexposed that can be corrected by brightening up the video later. But if it's too underexposed, when you brighten it up, the footage will be too noisy, or the details will be lost to the compression artifacts.
Very good tutorial - more people need to see this and take note, especially the 'flat earth' photographers!
So true. IT's almost as though they don't believe in focus, as dumb as that sounds.
I'm sure many (most?) of them know fine well it isn't in focus, but the blurry, shimmery balls they're showing gives them an excuse to shout about NASA and science being "lierz!".
Anthony Rodemus
They think there are "waters above the dome" so if their image looks like it's distorted & shimmering due to flowing waters they assume that's the correct & best view of the object, never mind all the controls available on the camera: those were just put there by NASA to confuse people.
OMFG you're so right, the reason im searching this is because of those idiots
Thanks for the info, will give it a try. I love my P900 but pretty disappointed that Nikon didn't give the camera unlimited flexibility in manual mode. Likely technical reasons why but still disappointing.
They fixed most of the flaws in the P1000
Now do one with stars?
ua-cam.com/video/Fe-b83oajPI/v-deo.html
@@MovieVertigo Thanks
Hey Mate, This is certainly something Im looking to do on my own channel at some point so thanks heaps for sharing your knowledge.
No problem. Glad to help!
Very helpful
Glad it helped!
Can i do the same with p600?
I don't know anything about the P600 I'm afraid
Movie Vertigo okay
Great Work!!!
does this work with pictures>?
The manual focus works for pictures. The light technique isn't necessary though as you can manual control the shutter speed and therefore the exposure when taking still images.
Movie Vertigo i was trying to take a close up picture of some stars last Night and they end up looking blurry like your comparison pictures and I don't know what I was really doing wrong so you're saying I need to put it in manual mode to be able to get them to come out clearly? Sorry this is my first camera...literally got it a week ago and trying to feel my way around
The P900 has trouble focusing on small light sources at night (e.g. stars & planets) so you have to manually focus in this situation, yes. Larger sources such as the moon, it can focus on fine in auto mode.
Movie Vertigo thank you so much!
Great video! And flat-Earthers film Venus and try to tell us that it isn't a planet all because they can't figure out how their camera works. It's unbelievable! I've always figured it was some focus issue, because I've seen Venus countless times through my telescope and it looks nothing like the weird camera shots. It looks like an actual crescent like this.
"all because they can figure out how their camera works"
all because they *can't / cannot* figure out how their camera works
Apollo 959 Thanks for the correction
This is what I am taking about
Thanks a lot ❤️
Any chance telling me the way to lock the exposure for canon sx60hs? 😗
Sorry, I know nothing about that camera, but maybe someone else will respond.
Nice and informative tuitorial...
Glad you liked it
Very good video. Thank you
Really impressive, you obviously know what you are doing. I have a P900 but I'm only a novice so thankyou for this. subbed
Thanks!
90 thumbs down out of 727? Does that mean 12% of the population is flat earthers? Stop the world. I want to get off.
Yep, it's the good old Dunning Kruger Effect... en.wikipedia.org/wiki/DunningKruger_effect
Great detailed instruction. Don't worry about the negative comments because the probably don't even own a camera
when I get mine I will try this. It seems that most of the problems with this camera is the operator .
How far do you zoom out when you make these adjustments?
The adjustments are made at full zoom
@@MovieVertigo Okay. Thanks.
The last step wouldn't work. I put a light in front of the lens but it won't adjust.
Was the camera recording when you tried it?
I replicated your settings before hitting record and then again while i was recording (introduced the light both before and during) but neither instances produced a clear image of Jupiter. I'm stuck with a white blob of light or the funky glowing/pulsing cell.
I got the AE-L locked while my light was shining but Jupiter doesn't look like the Jupiter in your other video.
Once you've locked the exposure, try adjusting the focus again.
AE-Locked and adjusted focus, but once the image was clear it was a tiny Jupiter. Jupiter has been the brightest I've ever seen this past month but how close is it cuz your other video had a huge image of Jupiter.
Thanks. Really needed that information and tutorial. That was the missing link.
Superb points and thanks. I did these mistakes with my P900 shootings
Well done if the moon is up you can also use it as your initial light source
Great,nice work, thanks
Does shining a light into the lens work for taking still images as well? I got a good shot of Jupiter and 4 moons last night but it is overexposed and looks like a white ball. I was using the "moon" setting and tried using negative exposure compensation but it didn't do much good.
You don't need to use it for still images as you can just set the exposure manually in manual mode.
@@MovieVertigo Thanks, I will give it another shot tonight if it's not to cloudy.
Thanks for the video.
Because of many new star and FE videos I bougth a P900 also.. and have realised that they have focused incorrectly.
No hablo mucho inglés, pero tienes un tutorial de cómo hacerlo con Júpiter o Saturno si es que se ven raros? :v?
The same method will work for Jupiter and Saturn.
El mismo método funcionará para Júpiter y Saturno.
Muchísimas gracias.
😊🌹
Thank you! Very clear instructions
man great video
Thanks!
@@MovieVertigo i have a question you said P900 doesn have long exposure option do you know which zoom camera has it
@@yoichifranck3753 It does have a long(ish) exposure at ISO 100 of 15 seconds, but this gradually reduces as the ISO is increased. At maximum ISO, the maximum exposure is 1/2 second. If you want to do long exposure photography, I'd recommend a proper DSLR/Mirrorless camera.
@@MovieVertigo man thanks for the info
Thank you for this. I had the focus Down, but didnt know how to fix the exposure problems i ran into when filming Jupiter and Venus. Will try the external light source NeXT time, Thanks
Glad I could help!
music please?
The music is Island Paradise from www.purple-planet.com
thanks
cool. so many settings and techniques.
Does Venus look like the moon because the shadow of the earth is cast upon it?
No. It has phases, just like the moon, where you're seeing both the illuminated side and the dark side. More info here... en.wikipedia.org/wiki/Phases_of_Venus
That's great thanks. I have one question however... Due to Venus being so far away, why isn't it just a case of setting the focus to infinity?
Most modern lenses can focus beyond infinity, so just setting maximum focus doesn't work, and the P900 doesn't seem to have an easy way of finding the infinity position.
Oh nice, zoom into a satellite please
Sure! Here you go... ua-cam.com/video/vZ476gBSEXs/v-deo.html
How did the image become so small after all the adjusting? Compared to the size before adjusting?
When the light isn't being focused correctly it's spread out over a larger area of the camera sensor.
Watch this video and see the same effect happening with plane lights. See how the light is spread out when unfocused, and small when focused... ua-cam.com/video/6sncmX0mNqM/v-deo.html
Thanks for this quick and effective guide !
nice tips! I knew how to focus it, but didn't know you could use light to lock the exposure, going to try that, thanks! I unfortunately just posted my over exposed Venus video minutes before finding this.. lol! Guess I'm going to have to re-do it!
Let me know if you re-try. I'd love to see!
I will be 100% I'm literally just waiting for the clouds to go away lol I love filming the stars/planets
I have now re-tried, and got better exposure, you can find it on my latest video :)
Beautiful explanation, merci beaucoup.
This is great tutorial! Thanks!
Flat Earth Talk Strange that you're here, considering that flat earthers love to use out of focus pictures of Venus to show it "isn't a planet" but a "luminary".
Gabe G or he isn't a flat-earther
Gabe G
shallow, vague, biased, or indoor "research" is hardly open-minded.
Perfect! Thank you very much! I will try tonight!
Thanks for great advice and a lovely relaxed video a thumbs up from me!.
If you switch to 'focus on infinity' can't another object come in focus, other than the one you aimed for?
Anything who's distance from the camera is within the "Depth of Field" will be in focus.
thank you so much for this tutoral i will try this when i get a nice clear night. thank you once again
Thank you so much for making this so simple! Im a new photographer and just got my P900! Im overwhelmed at the functionality. Its pretty simple to operate but, I just needed clear instruction on how to zoom. Thank u and I subbed! ❤️😘
thank you for sharing, i learned a lot
Good tutorial, well done
Awesome!
