Although Canon does provide official C-log conversion LUTs, those LUTs are meant for their cinema line of cameras. They're too punchy, skin tones look off, and vibrant colors quickly turn toxic. That's why I created a C-log LUT pack specifically designed for log footage from cameras like the EOS R, R5, R6 and 5D Mark IV.
The LUTs convert C-log footage to rec709 without altering the colors, and can be used for quick turnaround, or as a starting point for further grading.
