I presumed that the raw footage was unaffected by dlog / cine too, but did a test yesterday.
I set up a shot and filmed d cin, d log and none colour profiles at f1.7 100, 200 and 300 ISO for each. Then did the same for f2.0 etc etc. This was mainly to test out best cam settings for aperture, noise and what not.
On the SD card, there are, obviously, noticeable differences between the different colour profiles, but I can tell you now that they certainly do affect the raw files. Obviously, they're raw files and so it doesn't matter too much, but dcin exposed the image quite a bit brighter than none or dlog on the raw footage, and this was consistent across all of my tests at different fstops.
Colour also varied slightly between none and dlog, but only noticeable if looking for it. But, dcin was definitely exposing the footage more, noticeably so when played next the raw from one of the other two profiles.
Again, its raw footage, so this extra exposure isn't really too much of an issue as it can be knocked back in the camraw settings and you still have all of your highlight detail etc.
I just wonder what the camera is doing to cause this. The profiles shouldn't affect the raw at all, but they do, weirdly, even though just slight.
