Sony SENSOR hack - seeing light differently
Вставка
- Опубліковано 5 гру 2018
- I recently had my Sony NEX 7 modified as a full-spectrum camera. Essentially this means the sensor will recognize the visual spectrum in addition to Ultra-violet and Infrared light.
By using various filters on the lens, you can achieve some interesting results by limiting the light spectrum for both photography and video.
This weekend I'm going on another Sony trip to shoot some astro photography with Stan Moniz. Make sure you check out his channel and subscribe!

Listen - if you want to do nothing but IR experimentation videos for the next month, I'm not gonna complain.
I like that attitude ;-)
Anamorphic Infrared. I've already done it but that would be fun to watch.
Agreed.
I love it as well, but it would be better with something interesting to look at.
It even looks like Ted went out to take dull subjects on purpose. I think it's possible to experiment AND take cool photos at the same time.
Would really like to see the results for people/portraits. Thanks
ir portraits...
I think they used a thermic camera in a videoclip for Earl Sweetshirt. Not the same technic but the results look a bit like in this video.
@@MoonWalkerTexsRanger check out Route 94 - My Love, they use the same technique... looks cool
it's like you're shooting with hasselblad, but just with different colors. perfect for BW, the colors are just different. also perhaps our eyes are just wrong.
I could tell lots of stuff about it that would be perfect for videos. I've been trying this kind of stuff for a long time. For example, I took a slightly different path into full spectrum, by using non modified camera; working around it was challenging, but I came to know many things that maybe no one has ever thought about. One such aspect was "ditching" the filters for a moment to try and use purely light sources alone. UV was never much of my thing, but the process of making a composite was very interesting, as often the IR shots could be very long exposures (late afternoon, f/5.6, ISO 100 @ 5') & unexpected results could be attained. My method of creating UV was to use a proper blacklight (many don't work well, so it was a rare find) & turning photo to B&W for compositing with visible and/or IR. With IR+VIS, there are many variations, even with a regular camera & 850nm filter, however, the process of creating perfect composites is still very complicated. If you really know what to do, almost any type of spectral response can be achieved, by modifying; for example, take a 850nm+normal image, both identical, & merge in PS to achieve greater sharpness than what you can with a full spectrum camera. A full spectrum camera might be better overall for capturing a wide spectrum at once, but one could learn to focus precisely in each spectrum beforehand.
I’ve just converted my old Olympus OMDE mark 1to full spectrum with a clip in IR 850nm filter. Works a treat
Great as always. Love to see your love for making photography. Inspiring.
An awesome intro into Full Spectrum / IR photography. Very well done! I am anxiously awaiting further videos from you on this topic. Thanks!
gotta see more of this Ted. Beautiful images great video as always.
Beautiful shots. Oh man where to start. I shoot a lot of false color infrared. And I have 2 filter suggestions that are incredibly unique
First the 550nm filter from Kolari Vision. It let's in a fair amount of the visible spectrum and the results look almost exactly like Kodak Aerochrome.
The other is the Hyper Color filter from Life Pixel. I don't know how they did it. But they created a filter that can capture false color raw images that Lightroom can actually read properly. And on top of that skin tones are preserved so you can get some very dynamic images from it.
I think that all I have for now, by the way I'm the same guy who dropped the capture one tip on Instagram! Hope to see you explore more niche photography ideas.
You're talking about camera use with a full spectrum conversion right?
@@xmlthegreat Yep it has to be converted in order for the filters to work properly
@@MaxRobertsdoesthings but for the second filter set is it full spectrum or IR only conversion?
Akshay Anand both are filters you can attach to a full spectrum converted camera that blocks a portion of visible light to limit it to IR and a little bit of visible light. Technically our could get a camera converted to hyper color and use any IR filter because hyper color has a cut off shorter than 550nm. But for example, you couldn’t put a 550nm filter on a camera with a 720nm conversion because those wavelengths are already being cutoff.
I hope that makes sense haha I’m not that great at explaining this stuff!
@@MaxRobertsdoesthings I think I get it. A camera converted to IR only could still theoretically use these filters. I'm really thankful that I read your comment else I'd I've missed that Lifepixel had that filter. I've converted a CCD point and shoot to IR and have used a piece of unexposed film that was developed as an IR pass filter, so I know a couple of things which mage it easy to understand what you meant.
Great video Ted. Love your channel!
Super rad look to the IR! Love the unique B&W look. Very tangible and so much cool depth to the images. Thanks for sharing something new and interesting Ted! Can always count on you for that. 😄👍🏻
Definitely make more videos with different filter wavelengths! This is really cool. I could see myself getting into this someday and it's really interesting stuff.
Inspiring video. I've played a little with both UV and IR. I bought a full spectrum modified camera on ebay quite a few years ago while I was still working, along with a collection of the types of filters you mentioned. I mostly used live view and full manual to get to the exposure I wanted because the camera's metering system couldn't seem to handle UV or IR. A tip I picked up for UV work is to do a manual white balance by photographing a piece of PTFE (Teflon ). You can also substitute a photo of a piece of typical city sidewalk concrete in a pinch. I've also used that technique to do the WB for IR with good results. The only other tip I can offer is to suggest trying out some of the very old single coated or uncoated screw mount lenses from the '60s and '70s to get into "poor man's" UV photography. It seems that many if not most modern lenses have coatings, glass, and / or multi element bonding cement that absorbs UV significantly more than the old lenses. I've found that old Petri and some Pentax screw mount lenses seem to pass UV acceptably. Also keep in mind that the various makes and models of sensors vary greatly in their sensitivity to UV, though IR should be less of a challange.
I think I need to watch a little less youtube and dust off that old equipment! Again, great video. Have fun.
So cool. The images are kind of creepy and I love it. Yes, would love to see more!
"Texas is not the most beautiful place right now" Man, me and a buddy were having this same convo last week. We both live in FtW, both travel, and both seem to never shoot when we are home. Might have to pick up an old Sony and try this! Thanks, Ted!
Would love to see more about the different filters and capabilities! Thanks for this video and all your videos!
Definitely want to see more.Nice video and info
Please do more on this :)
Also love te quality of the video and color profile
Hi, I have just removed the sensor filter in my compact camera and fitted a 72 infrared filter. Do you have any suggestions as to my ISO and white balance please. I have noticed that setting it to B/W everything is in monochrome, but if I select colour it picks up only blue items and the rest is monochrome.
NIce work, I had one of my Fuji's converted had lots of fun with it
Excellent thank you , ps what camera have you shot this video with , it is very sharp looking ?
Very interesting results.
You mentioned using a monochromatic camera, would be interested in a comparison between mono conversion and full spectrum. I do a lot of B&W and have been considering a conversation myself.
P.S. listened to your first podcast, Well Done!!!
Beautiful shots man!
Thank you, you opened up my eyes to a genre I hadn't considered, to the point I have just purchased an IR converted camera.
I have the same conversion, done here in Australia by a company in Melbourne, I have three filters, everything works well, if you live in Australia don’t spend money to the US for conversions. Nex 7 works well for infrared. I have been asked many times the company is Camera Clinic they have a detailed web site and very helpful.
Ah where abouts in Melbourne!??
This was much more interesting than I thought it would be. Now I need to convert my camera..
Super interesting results however way over my head when it comes to post processing. Love the info and YOUR presentation! Thanks Man.
A really enjoyable video, I have shoot IR a few times in my film days, like your self with various levels of success. Keep thinking about getting an old body converted as I do love the look but not been to sure on which to go with. Definitely something to look into more early next year.
So glad I kept my NEX-7! Time to dust it off and get it converted!
I’d love to see more on this subject!
Thanks for the video mate
loved it!
Thanks ....great video
GORGEOUS!!!!
The B&w images (pardon the too worn phrase) are epic. Keep ‘em coming.
what if you use calibration card like color passport ?
another great video of yours! I did some IR photography with film (rollei or ilford films), I would love to hear more videos of this topic! its a fascinating type of taking pictures. Now I am curious for the astro photography. go on!
Forgive me if this is a silly question, but can't we get similar results shooting with a circular polarizing filter on a normal camera with monochrome picture profile (or editing as B&W in post)?
Anyone knows where I can buy (items/parts) to cut & sand filter?
The filter that sees hydrogen-alpha wavelength is very expensive.
Then come the UV pass filter down to IR pass filter.
I would like to cut to have ATG to install onto Fuji GFX-100.
Looking forward to your hopefully soon upcoming UV-Video, when the filter arrives.
I love this! I’ve shot a lot of IR on 4x5 and I can’t wait to shoot some Kodachrome on the 8x10
UV Filter, basically your average anti UV blocking filter on the market a.k.a. lens protector.
In the old days is to prevent purplish haze on film camera in daylight because of UV pollution, today we simply use them for lens protector.
What you need is UV Pass filter, hence only UV spectrum being passed over; but you'd need specialized lens as well because most lenses does block UV lights with their coatings.
Either you'd use very old lens without anti UV coatings or some old nikon enlarger lenses (those known to not having anti UV coating because it doesn't need it for its intended purpose) or try to lap modern lenses without scratching it and remove the coatings (really hard to do correctly).
Also for some cameras with weak IR blocking filter, one could almost get IR photo with cheap high density ND/VND because cheap one they simply block/reduce visible light without additional IR/UV blocking (happened to me when trying fuji HS20 and vari-ND.
Hi Ted! I always find your videos very interesting and useful. Your channel is fantastic and I think It is one of the best in the photography category.
So. Could be interesting to point the sun, maybe doing a collage of different takes with several filters, maybe with a 4/500mm tele, an nd to not destroy the sensor and a bunch of other filters selected by spectrum (I know this technique is used in astrophotography to find and detect which gasses we observe, for example, in nebulas or galaxies..).
Anyway I wish to see more of this type of experiment :)
Thanks for your time! And good work!
Giuseppe
I'm looking forward to your future experimentation.
Thanks for making this video. I'm getting ready to take up IR photography, I have a Very Limited budget and have been looking at mirrorless cameras to get for the conversion. Do you still recommend the Nex 7? They are within my budget and although, I don't have the quality glass you do, your B&W are stunning. Thanks.
This brings back memories... I sat down and "hacked" a camera myself about two years ago. It worked out great but I think I've never been so nervous before! It's a lot of fun to experiment with infrared, would love to see some videos about that!
By ONLY removing the IR internal filter on the body, will you retain full AF and fast shutter speeds ? Ex : If j want to shoot birds in flight but in IR (DAYTIME)
AND ... of I ONLY remove the internal IR filter, will I get good results ant NIGHT with an IR light source on my subject ?
Thanks
I'd love to watch more IR videos :)
How many stops more light do you let in with the different filters/no filter? i.e. no colour filter is one stop brighter I think for B&W cameras
Seems really fun
There's a company that makes clip in filters for sony cameras, I know for a fact that they make them for the full frame sony's (a7 and up) and those come in the IR cut filters, Hydrogen alpha/OIII for astrophotography, along with ND filters and some others. They're really interesting to be able to have a clip in filter instead of having to thread them onto the lenses.
How can I buy an ultraviolet filter? That will allow me to do ultraviolet photography. Please help if you have any suggestions.
Your vídeo just gave me a cool idea. Those high contrast IR filters would be great for making high detailed masks for photo compositions! Gotta search that up!
May I ask what lens are you using to film @3:48?
Ted, if you purchase a UV filter, please, test the following the next spring. According to what I was told, flowers that have not been pollinated yet, radiate in the UV with a pattern that looks similar to landing lights for the bees and bugs. Once the flower is pollinated, this UV lights are turned off.
Those marks are there to show bees where they should go, but are permanent - flower can't switch them on/off.
I’d love to see more ir stuff, super interesting
I have done some IR work with borrowed cameras that have been converted and gotten some cool results, but never did the conversion on one of my own bodies. I like this approach a lot! How do people look in an IR or UV image?
Hi, I’m looking for a in camera picture profile for Sony A7riv that will give be a Leica Monochrome look ?
This is only half a story until you give us the portrait one!
Yes very interesting great stuff
I really enjoyed your video and have been shooting infrared for more than 20 years. I travel a good amount (in dusty places) and have settled recently on having an rx100v converted. Though I'm limited to not such wide lens, I don't have to worry about dust and in my experience, dust has been a HUGE problem. I did a short film on Angkor Wat (Cambodia) a couple of years ago all shot on infrared. Keep up the great work-you made a subscriber out of me, which is very hard to do :-)
Do you have to remove bayer filter too? If not, I still don't understand how this modification works!
If you have a full spectrum shot, a spectrum minus UV & IR and a shot of IR only then surely you can post-process it to get UV only?
Dear Ted, I like your explanation of light with a digital cam. I Will watch iT again next Year, because richt now i am hooked on my dads F3, and with your help I have already shot Some 10 rols, tri x 400 and tmax400. Not one day without your lessons 🤓😍! L❤️u
You can do this easily with Sigma Cameras as they have a removable IR filter, they also have no color filters unlike Bayer as the silicone itself filters the light as it passes through to each of the three layers.
The workflow is more complex though. I have an SD1. But using my full spectrum A6300 is much easier.
@@EdHecht you can shoot DNG with the Quattro chips
very interesting video!
Whats the dynamic range on these photos?
Very cool! I dreamt of converting my old D70 some years ago ... but sold it instead. Any recommendation for a Nikon-conversion?
Can you tackle the ‘hotspot’ issue. I have a converted XT2, and landscapes are a popular subject choice for IR, but many/most wide angle lenses will produce a hotspot when working in IR. I just try and work around it, or compose in a way that allows for it to be edited out, but it’s super annoying and quite restricting. Aperture settings help reduce hotspot, but don’t eliminate it altogether. Any info would be appreciated. Cheers!
From what I've read this is due to different lens coatings behaving differently in IR. If you Google "lens IR hotspot list" there is a list of a lot of lenses and their IR performance.
Amazing!
I have been tempted to do an IR conversion when I upgrade because summer in California is brutal for photographers (there is just so much bright light). The full spectrum upgrade seems like a good idea because I have been thinking "what happens if I want to take a normal picture", I didn't want to carry 2 cameras. If you have extra reading material please do provide links. Would love to see details (including rough cost) of the conversion, more details about filters, and any assets that may help in making the decision to convert.
Have a look at Lifepixel. It's possible to do the conversion yourself and the difficulty level depends on the brand. Don't try it with Fuji X-series, I learnt that the hard way.
If you have a cheap point and shoot (especially the older Sony ones with their wonderful CCD sensors), you can usually convert them yourself for the IR band. It involves removing a small glass filter pane from the lens assembly and then putting the camera back together. Then use unexposed film that's been developed as a visible light cut filter. Et voila, an IR camera. Full spectrum is a bit harder.
Thanks for the replies Floyd and Akshay. Depending on what happens I may try it in the spring so that I am ready for the California summer.
A common misconception with infrared is that it’s all about summer foliage in the mid day sun. I work in infrared at any time of day in any weather any time of the year and get really interesting pictures. Infrared in snow and ice for example, is just amazing. Once you get past the honeymoon weirdness phase, everything opens up.
I really want it for shooting ir in Manhattan. With all the electronic interference it should be wild
Great video
What camera did you use to film this video?
0:41 Actually, Infrared is BELOW the visual spectrum and vice versa. The bigger the wavelengh, the lower the frequency. In this therm, higher frequency means up.
Great subject to explore more. Everything around you is new again when recorded in a different light. As a teen in the early 70's I shot a number of rolls of Kodak B&W Infrared (with a #25a filter) and color Ektachrome Infrared (with a #12 filter). I even tried other filters just to see what came out. On occasion I open my boxes of history and relive the wonder of the invisible. Now you've shown me that I can do it again with the instant gratification of digital photography. One more project for when I retire !
I used to work a few blocks from a company called MaxMax in NJ that did IR, monochrome and other conversions on cameras. I was so tempted to have my old X-100 converted to monochrome but ended up selling it to fund other stuff. While not cheap, the image quality from a true monochrome sensor beats any B&W conversion done in post. And a converted camera is still half the price of a monochrome Leica.
I bought a Lumix GF6 with a IR adapted sensor last year.
I love it, one of my most liked pictures on insta was an IR photo, shot with a 12mp M4/3 camera.. ;)
Nice job! I would like to see more IR & UV work :-)
Why not Sigma SD Quattro which has removal IR filter? One can do it without the expensive conversion process or shipping back and forth.
0:36 First you talk about "in terms of light energy" and then say that UV is below visible light. In terms of energy (per photon), UV is above visible light and IR is below. You were thinking in terms of wavelength which is inversely proportional to energy.
If you use a #12 or #15 yellow filter on your full spectrum camera, the blue channel records mostly IR. That way you can swap the channels RGB>BRG and get a decently convincing Aerochrome look.
Is there a way to focus in infrared on the camera by offsetting the auto focus
Just use live view for focusing on a DSLR. If you have an electronic viewfinder the focus should be accurate. I had my EOS 40D converted to IR some years ago and the guy doing the conversion told me he had adapted the autofocus to IR. But most of the time I use it on a tripod tethered to a tablet check manual focus in 10x.
Infrared content is pretty interesting. Definately hope to see more in-depth of it
depending on the image and with what filter it was taken, inverting it with an adjustment layer in Colour blending mode or inverting A or B from Lab model, can provide a good start, when working with Infrared/ Full Spectrum images.
Zomei (Chinese) makes dirt cheap IR filters readily available on eBay at several levels 560, 720, 850mm and higher. They work just fine on my own full spectrum A6300.
This is interesting since one can do NDVI plots of certain regions with just a camera like yours. Possibly creating amateur remote sensing applications. Very fascinating! Thank you for the video. Imagine if you could create a FlyEye method, you can map the whole region around you with more information than normal. Its more intricate than what I am saying, but this fun. I am currently working on a similar tech currently.
The NEX-7 is one of the most sexy beasts Sony had release.
By the way Sir. Those are some amazing pictures!!
With sony f717 you only need a strong magnet to modify camera temporary. Quite amazing results when you think about the camera that you can get for about 20 euro with a great lens and "modification" takes 2 seconds and is reversible by restarting the camera.
Is it still possible to IR film would love to know thanks
Cool!
I love this
That looks amazing *.* but I thought there was an ir filter that you can place on the sensor yourself for canon cameras so I am not sure.
But I think I am gonna try it with film because it's also very awesome
Would be great to see flowers in UV. You can see all the signs and arrows they have that help designate pollinators where to go.
very interesting video, Greetings from Germany
I took infra-red images back in the old days of film cameras. Back then you had to alter the focal point of the lens when taking pictures, as infra-red focuses at a different point to normal light. How do you get round this with digital?
I was curious about that also. Especially since UV & IR are at opposite ends of the spectrum and focusing for one would not even be close for the other.
Stopping down the lens would help with this as it does with chromatic aberration of visible wavelengths
Will you compare with Ilford SFX 200?
videos in this interesting style would be epic
Wowza Ted, beautiful.
Hi Ted. Great intro video into the world of IR photography. I've got my A7R converted some time ago and use filters from a Taiwanese company called STC. They clip on right in front of the sensor so you can use just one filter for all your lenses. Brilliant!!! I've got an ND1000, an Astro and an IR850nm from them. Check them out from an easy STC filters Mr Google search. Can't believe I only just recently found out about these things. Anyway, I also wanted to say how jealous I was that you got to go on your first Astro trip with Stan Moniz. Wow... what a way to start into astrophotography. He indeed is a master. Hope to see a video report soon about it. Cheers.
I wonder if you can modify a black magic pocket 6k to film in IR.
Is it precision camera in AUSTIN TX or the one in CT?
