Canon C200 Gamma and Color Matrix Test
We were recently faced with the dilemma of choosing which recording format to go with on the C200 - the more expensive, data-heavy, 12-bit Canon Raw Light or the lesser, cheaper 8-bit .mp4. We were covering a series of instructional videos with three cameras rolling simultaneously so I decided to go the .mp4 route. Of course the difference between the two is in the details and not many viewers would notice any less fall off in the shadows or increased clipping in the highlights. The smaller file size gives us less flexibility to correct in post so we wanted to make sure that what came out of the camera was as close to the final image as possible. We decided to run a studio test to determine which combination of gamma and color matrix would gives us the best result.
A few takeaways:
- The different color matrices give us very subtle changes in skin tone. Notably, the Neutral, Production Camera and Video options cause the skin to look a little red while Cinema EOS Original and None look more natural.
- When shooting Wide DR, it seems as though the overall exposure gets boosted. I changed the ISO from 800 to 500 to try and get the exposure on her face to match that of C-log.
- C-log 3 looks a good deal darker than C-log
- Having no color Matrix gives you the flattest, least saturated image (maybe that was a given)
In the end, we went with the Wide DR gamma and Cinema EOS Original color matrix to give us a clean look right out of camera.
