The previously announced Canon-Technicolor joint picture profile, "CineStyle," is now available for Canon DSLR shooters as a free download. We'd heard from Technicolor that the picture style would allow for greater control and latitude, but the question on everyone's mind is, how much can a picture setting do without changing the limited 4:2:0 h.264 codec? I haven't put it to the test myself, but crooked path films did:
The official CineStyle flat picture style looks better to my eye than some of the user-made files out there, but it's still constrained by the color space and codec. However, in over- and under-exposure tests, the Technicolor profile holds sharpness much better. Also see some tests from Vincent Laforet.
