Canon EOS Cinema C300 MARK (MK) II - Canon LOG Tests
Below are frame exports from Preset Picture Profile tests using Canon Log 2 and Canon Log 3, with different Color Spaces both with Canon's correct LUT applied and without. I also included Canon-EOS-5D-Mark-IV-ITUR-BT.601-No-LUT, which was taken at the same time with the Canon 5D MK IV Standard Profile, which uses the BT.601 Color Space in 8-Bit 4K 422.
Conclusion:
I'm quite surprised how close the colours are, apart from DCI-P3 which is pretty vivid, also note I did not change the exposure when shooting and made no corrections in post prior to exporting. Even the 5D MK IV file is not wildly different, probably a tad over saturated but colours are pretty spot on, from what I saw when shooting.
