White Balance Filter for Infrared? Raw vs JPEG, IR Video, ExpoDisc 3

[@wooddogg8]

Thanks for all the info. I've had a full spectrum modified Canon 90D for years now that i use for astro photography with great results. I've finally ordered a couple of IR filters for daytime use. I'm sure it'll be a learning experience but I think I'll feel like I'm really getting full use out of my camera. I'm excited for the journey! thanks again!!

Rob, thanks for another informative video.

Thank you Rob. Very interesting 👍👌 And indeed your very right about 720nm. That's why I pick up years ago to start my IR photography journey in a SOOC (jpg only) way with very good result on a converted Fujifilm X-E1 720nm. With that I have very little to none post-editing to do 🙂 And also thank you for the exemple provided with the IR Chrome filter. Your results in jpeg are very consitant to my results with my Fujifilm FS converted camera. Great 🤜🤛 I'm realy with a FS camera and with IR Chrome or other IR filters (like Infra Blue) an advocate of doing custom WB (and as you remarked everytime light conditions is changing, in fact for me nearly at every shots when I'm moving around). For achieving good results I'm using for the moment an IR white card. Expo Disc is another way to go 😉Nice info.

Learning everytime I watch one of your videos! Thanks!

Thank you Rob … always pushing boundaries and Marin me think.

The way I learned to use the Expodisc was to aim the camera at the light source (for instance, the ceiling of a gymnasium with vapor or other artificial lighting at a basketball game) - since that is where the color temperature from whence the light is emanating. But the entire color balance thing is about rendering truer colors in situations where the lighting that is illuminating the subject has various temperatures (say, a combo of fluorescent and incandescent) - so rather than everything having an overly warm appearance (or whatever) the image looks like it did to the people viewing it live. However, since there is no such thing as rendering accurate coloring with IR, this does not seem to make that much difference. DOn't get me wrong, I enjoy shooting IR and have Rob's profile sets for the Fuji X-S20, but don't see any real benefit to the Expodisc, which I do use in venues where the lighting is funky.

Thanks for your videos! I still need to optimize my IR editing setup a bit, but I think you've given me some good ideas on how to do so!

[@FrankCrispo]

Always very informative. Thank you!

[@BrianSFischer]

Thanks Rob!

I had never thought about making IR videos! They look pretty cool! I see you're using the studio version of that program which I don't mind paying but can I color swap in the free version? Also if I don't use the LUTs can I still swap colors? I've never used DaVinci

[@robshea]

Yes, you can use LUTs with the free version of DaVinci Resolve. I picked up the Studio version last week and had been using LUTs with the free version before that. I have not tried swapping colors without LUTs. I also have free LUTs available for you to use. 590.red/lut2

Rob question please? The Expo Disk would be VERY helpful in my IR workflow. The question I have is for filters that suggest you WB on grass and foliage (830nm or 720nm), would using the EXPO DISK 3 aimed at light work instead of WB on grass? Thank you.

[@robshea]

An 830nm filter captures no visible light, no color, so you don't need to worry about white balance. The result is monochrome. With a 720nm filter, white balancing on foliage will produce white foliage and white balancing on neutrals (clouds, pavement, buildings, etc.) will produce lightly saturated foliage. An ExpoDisc will give you the result of white balance on a neutral subject and lightly saturated foliage.

@@robshea Thank you for the reply and your videos. I have your great presets.

[@sklba632]

That red battery life while you're doing your settings had me nervous, lol.

[@robshea]

🤣

Hey Rob, Your IR video got me interested in photography. I bought budget canon 450D/XSI camera and converted full spectrum IR. Have all necessary filters for shooting. I am running into blurred images. Any suggestions?? Also if you have any video done on free version of editing software? Thanks in advance!!

[@robshea]

Ensure that you focus with on the live view screen and NOT the optical viewfinder. The optical viewfinder focus is calibrated for visible light and will not be accurate with infrared. darktable is free.

[@herbbrail3771]

Will the same results be obtained using the ExpoDisc 2?

[@robshea]

I have not tested the ExpoDisc 2. From their FAQ: "We developed a new combination of diffusion materials and are now able to test the ExpoDisc v3 from 300nm-2200nm. The new ExpoDisc v3 exhibits even better light transmission with optimum performance from 380-1600nm. In the visible spectrum of 380-700nm the delta is just .9%, and from 380-1600nm it is just 1.8%, which means the ExpoDisc v3 can now be used for IR photography." www.expodisc.com/pages/expodisc-2-0-faq

Hi Rob! I'm really into IR photography since watching your videos on explaining it. Could you make a video about ''night vision'', I didnt see any professional talking about it, only in niched forums with no tutorials on it. Do I need only IR lens? Do I need to full convert camera? Can I just buy a old camera? Do I need both lens and IR light spotlight? Thanks for the awesome videos man. footage example: kzbin.info/www/bejne/fIvPc4V9d8lpfdU

[@robshea]

Here my short take on "night vision". This uses a camera that either has been converted to full spectrum, has been converted to a infrared high-pass filter, or has a weak hot mirror filter that allows near-infrared light to pass. The camera is then sensitive to near-infrared light. When you pair this with an artificial LED light that emits mostly infrared wavelengths, your full spectrum camera will detect the IR light, while your eyes will only see dim red LEDs.

@@robshea that helps a lot. thank you so much rob!
