I use an IR/ND filter on my EX3. Without it on hot days, skin tones have a funky fake looking tan. Other things started to turn organe. I’d hate to fix that pollution in post so I opt for the quick camera fix…even if I lose a stop.

Do you seriously like the BMCC sans protection? (I’m honstly asking, not being disrespectful.) Check out 2:45 of the first video – the blacks are bright purple. According to Micth the BMCC needs IR potection almost straight out of the gate. (With low levels of IR.) If this is an effect you like, or don’t mind that is one thing. Accurate and precise colors are a different issue.

Even with RAW images IR is still a problem if your goal is accurate colors and skin tones at the end of the process. I have 5k RAW files available for download here if you want to play with them for yourself: http://www.ryanewalters.com/Blog/blog.php?id=4094508292434585142

The problem these days, and demonstrated well in the video examples, is that different cameras need different solutions. If you only use one system, then only one solution is needed. I use multiple systems, so I’m looking into solutions that work a cross multiple camera systems … Lots to figure out on this end, and there doesn’t seem to be any one answer for everything unfortunately …

IR is definitely a problem area. I first encountered it with the Sony F-35 with 12 stops ND in front of the lens. This was before IR filters were standard filters as they are now. The leaves on the trees went brown. The only fix was to use the built in ND wheel on the Sony, just like the old time video cameras had and some new cameras still have. The internal ND wheel also blocked the IR. Worth a try if you have that style camera. I also ran into this on some accidentally underexposed Canon 7D footage. It can’t be fixed in color correction, just manipulated a bit.
So, great, informative video. IR will surprise you if your don’t prepare for it. Thanks!
Best to you and to all on your projects.

So far, I’ve had no problem with this issue. It’s nice to see people considering it, but I don’t think I’m going to spend a lot of my time worrying about infrared light.

I believe the 5diii has a built in IR filter. I wonder if it’s the same as the ones on the cinema cameras. Just starting to shop for filters for my Tamron 24-70 and was considering the need for IR on the NDs.

I was thrilled to see Canon clearly has decided to fix this “in-camera”, which is always preferable to fixing it in post. Since C300 and C100 have an identical codec as C500, these are truly good working tools.

Why surprised about the Canons? The C100/300/500 all have a hot mirror-style IR filter built in between the lens mount and the ND filters, and it serves to seal all that works so your NDs and sensor don’t get dirty. No need to worry about this or a lot of other things it all just works.

The Canons are very well designed and implemented. I get a kick out of people who hate on them. But at least we’re all not shooting on the same camera.
