Spencer, I've watched several of your videos so far, and I have watched hundreds of other UA-cam photography videos. Your videos, particularly the ones where you focus on a specific subject, such as this video, are the most comprehensive videos I have ever seen. Your videos are always interesting, entertaining and very easy to understand. I am a reasonably experienced photographer and I indulge in various genres, yet I find myself learning something from every one of your videos. I am very glad I found my way to your channel. Please keep them coming. Your channel really deserves some recognition
Wow, thank you! That means a lot to hear. I had to take a hiatus on new videos for a while, but comments like yours are why I’m so excited to start again with a vengeance early next year.
You are extremely thorough. I've watched a lot of videos about aperture and you're the ONLY one who talked about lens diffraction, distortion and flare! Those issues may not sound important, but they can ruin a good shot. I'm subscribing.
Me before watching this: I'm not a newbie to photography anymore Me after: I should go back to gaming... Very accurate title, a lot of very useful info in a 10 min video.
Glad I found you, dude!! Love your presentation. You put it in very simple wordings understandable to neophytes in photography like me. Will surely follow your work again. Thank you so much. :)
Absolutely brilliant explanation !!; as a new photographer and on a steep learning curve your tutorial has short circuited the understanding of the effects of Aperture; thank you...........
Thanks for sharing your experience with great comments..... video has helped me understand more about aperture....I am only a hobbyist but always willing to learn more about photography.... cheers from Australia 😀
It has been 35 years since I took a photography course, and I needed a refresher on Aperture for my new to me DSLR. This was an incredibe video. Very thorough, easy to follow, and definitely worth my time to watch. Thank you for the excellent refresher. I'll definitely watch more of your videos.👍👍
Bravo! I'm not a photographer but have loved all types of photography for many decades. Your tutorial opened my eyes and appreciation to the techniques used. Thank you!
Thank you, Silvia! I was planning to have music over those sections initially, but when I heard the sounds of the leaves rustling, I couldn't resist leaving it as-is :)
Great video! One of the hardest things I have tried to understand is, in my photography workflow, how do I know which aperature setting to use? I understand the concept of DOF and using the aperature to improve lighting but... why F11? Why not F13, 16, 22? This is my mystery. Dave from Virginia Beach.
Generally, the “middle” f-numbers like f/5.6-8 will have better sharpness, and the farther away you go in either direction, the more image quality you give up. But very often, you will still need to shoot at different apertures to gather more light or get more (or less) depth of field. You’ll know which one to use based on practice - for example, does this scene need so much depth of field that you have to be at f/16? Or are you safe at f/8? Take a photo both ways and see which one is sharper, then learn from it when you look at them back on your computer.
Hey Spencer, thanks for this nice video. You know what, event you count so much effects of the aperature mechanism, you forgot to mention the change in chromatic aperation.
Quite true! I skipped over a few lens aberrations, including longitudinal and lateral chromatic aberration, astigmatism, and others, because there are so many of them. These particular aberrations also tend to follow the trend of more aberration at wider apertures, although occasionally you’ll find a lens that gets marginally worse with lateral CA as you stop down.
I have photographed since the late seventies. I would have shown an aperture close up, and I may have explained the numbers. But apart from that, I would say this is unusually accurate. Some effects are much less important, but he also does mention that. Well done.
Very comprehensive Spencer! I have a question I've been curious about and it's related to the last segment in your video. Some times when shooting in dim conditions I will auto focus at f/2.8 and then stop down to say f/8 or f/11. This is usually focusing at about double the distance from the closest object, and using back button focus. I have not noticed that focus is impacted but I'm also not sure if this is an advisable technique. Is the focus shifting when stopping down? Hope this makes sense.
Definitely does make sense, but luckily focus shift isn't an issue whatsoever in that case. It's really only visible when making small aperture changes from roughly wide open to about one stop smaller. In fact, it's common for a lens's focus point to shift *back to the original point* once you're 2-3 stops down and more. All this is on top of the fact that even the worst focus shift lenses will almost never experience it to such a degree that it seriously harms a photo. And at f/8-11, your depth of field would hide it all anyway. In short, you have nothing to worry about!
@@PhotographyLifeChannel Thank you Spencer! Really appreciate you getting back to me on this. Really interesting to know and glad this technique is pretty safe to use!
It’s called the ESDDI TP-60. I just got it a couple weeks ago as a cheap secondary tripod, since my old one broke. It’s not a great tripod by any means, but it does punch above its class (at about $100 including the ball head). Hope this helps!
This is a really well explained video! There's actually something related that I've wanted to ask for a while, if you don't mind: When I do star photography, I find it difficult to do photo stacking. Specifically, I think software gets confused by aberration (probably mostly coma), which makes it hard for it to align the photos. I know you have a lot of experience with stacking (I followed your Photography Life tutorial the first time I've tried it :) ), so I was wondering if you've encountered this problem, and what you would recommend to do (I use the Nikon AF-S NIKKOR 20mm f/1.8G ED lens, and Photoshop). Is there an app for Windows which you find gives good results?
Thank you, Natalia! I'm assuming you're talking about image stacking to reduce noise, rather than panoramas or focus stacking. If so, Photoshop does a pretty terrible job dealing with misaligned stars. If you have foreground elements in your photos, your best bet is to use Sequator (Windows only, free); Mac users should use StarryLandscapeStacker instead (Mac only, $40). Also, make sure that the TIFF photos you import to either software don't come from Lightroom or other software with automatic lens corrections built in, or it may have a hard time stacking them. Both Sequator and StarryLandscapeStacker have tutorials online telling you their recommended import process. I hope this helps, good luck!
Thank you so much, Spencer! I'm relieved to hear that you had the same experience with Photoshop, I thought that perhaps I was doing something wrong. I'll be sure to check out Sequator next time I do some star photography!
I likely will at some point, but in the meantime, I recommend looking at a chart of all the full stops and 1/3 stops. (The main full stops are f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, and f/22, although there’s technically no limit in either direction). These aren’t random numbers - if you notice, every two stops doubles the number. The “f” stands for “focal length.” So if your focal length is 20mm, and you are at f/2, you can actually plug it into the equation: 20mm/2. That of course equals 10mm, which is the physical size of the aperture blade opening when viewed through the front of your lens! So, even though the numbers are weird, they are not meaningless. When someone says to change aperture by 2 stops, they are saying to go two full stops in one direction or the other. (So if you’re already at f/4, they’re either saying to “stop down” two to f/8, or “open up” two to f/2.) I hope this explanation helps, but let me know if you still have any questions!
No kidding! It’s something I wish Nikon would put on their mirrorless cameras too (I shoot with the Z6 - enjoyed the EOS R when I rented it a couple years ago too.)
Hi! I wanted to ask, since my lens is not expensive and its aperture increases when I zoom (which I just recently found out was not “meant” to be that way), how does this affect the utility of aperture?
Nothing wrong with that, plenty of zooms are variable aperture. All it means is that your range of available aperture values will change as you zoom. If you’re shooting in low light, it can mean that it’s best to zoom to the widest angle so you can use a wider aperture. Other than that, it doesn’t significantly affect how you’d use the lens. (I’ll add a quick note - the aperture doesn’t increase as you zoom in. Because aperture is written as a fraction, an aperture like f/3.5 is *larger* than an aperture like f/5.6. In the same way that 1/4 is larger than 1/8.)
@@PhotographyLifeChannel Thank you for answering! My problem with this is that in low light it’s difficult to get enough light in that often I have to increase the ISO and/or decrease shutter speed. Also because the biggest aperture I can get is f/3.5. Though I’m still a beginner so I maybe I will learn ways of dealing with this (besides buying a better lens). Also thank you, I learn so much from your clear explanations
Call me a plagiarist, but I to sum up my opinion I just need to copy and paste 'marios' opinion below. But I won't. But I will give it 👍👍. Thanks Spencer.
Good question, but no. The aperture values represent the diameter, not the area, of the diaphragm opening. Double the diameter is four times the area, AKA four times as much light that passes through the lens. Hence why each full aperture value (f/2.8, f/4, f/5.6, f/8, etc.) is one stop brighter than the previous. You could also think about it in terms of exposures on your camera. 1/100 second at f/4 is equivalent to 1/50 second at f/5.6 if you’re after the same exposure.
@@PhotographyLifeChannel I see! And by increasing the stop in this instance, the depth of field becomes wider but the exposure stays the same! Thank you for answering the question though, it’s double the light between each stop, thank you!
@@robinsievers2756 Sure thing! And that’s exactly right. Going from f/4 at 1/100 second to f/5.6 at 1/50 second is precisely how I would increase depth of field without changing the brightness of the image.
In the first example, he explains and shows how the brightness changes depending on what aperture you are shooting at. Though in the second example there is no difference in brightness. I don't get it! 😕
Sorry for the strange question. But is the voice dubbed in this? It looks perfectly synced but you sound like you're indoor with the reverb of a small room for most of it. I find it really distracting.
There isn't anything left to speak about aperture after this video. As usual fantastic job. God bless.

can u plz make a video on F stops.. how do they calculate.. its very confusing to me when some one says 1/3rd fstop , or 4 f stops etc...

Why I love eos r, closes the sensor when ya change lenses
No kidding! It’s something I wish Nikon would put on their mirrorless cameras too (I shoot with the Z6 - enjoyed the EOS R when I rented it a couple years ago too.)
In the depth of field segment, how were you able to have such a narrow aperture and still so much light?
Similarly, in the sun star effect segment, how are you able to take low light photos with a narrow aperture?
I just used a longer shutter speed in those segments!
