Most of us think Canon has the best color science of all players in the industry. Period. Many of us think Fujifilm follows close up.
Denae & Andrew posted a rather interesting video where they compare Canon and Fujifilm colors. They used a Canon EOS RP and a Fujifilm X-T3 for the test. Both raw and JPEG files are compared, though it makes more sense with JPEG images in our opinion (at 5:37min in the video). One thing I like a lot in Fujfilm cameras are the film simulations. Wish Canon would feature something similar on their cameras.
According to the comments to the video, people seem to like Canon colors more. What do you think?
