hello again, it's been a while :)

i have recently added the Mark II and now using my good old Mark I as a B-Cam, going now on a documentary style of job, and want the 2 to work together nicely.

after one week of using the Mark II i completely understand that it is utterly a different beast, so while i can't imagine a complete match of the raw material right out of the box, i'm now thinking of a strategy to make it match later in post.

considering that the Mark II is more dynamic and flexible, i just want to get as close as possible to the color of Mark I, that will shoot Wide DR.

does anyone have experience and can recommend me how to set up the Mark II custom preset in order to achieve that?

many thanks in advance,
Shai

From Travis Cossel of Black Label Film Studio in Miami:

"I just did a real test to match WB between C100i and C100ii using WB shift on the C100i to match the C100ii. You CANNOT do this via the LCD screens as the quality is vastly different and the C100i LCD is totally unreliable for color. Instead I took the time to record segments of footage on both cameras and ingested them into my edit system to compare...I dropped the shift down 3 (toward magenta) and over 1 (toward blue). Hope this helps those of you trying to match your C100's."

Duh. Seriously, if you eyeball on any camera's built-in LCD, you're just asking for issues. That should go without saying.

Just realizing that I didn't read Shai's question very carefully, ADD at work with me. He was asking about C300 MKI and MKII, not C100, totally different beasts.

I saw something in one of the white papers that led me to this solution. It's dumbing down the mark II substantially, but it was canon's approach to matching the cameras.

Shoot Canon Log or maybe Log3...(ideally in rec709) with the original cinemaEos color matrix, and then use the Canon Log to wideDR Rec709 LUT.

I've never tried it, so I don't know...but from my testing with that matrix, it is greener than the others, and that would seem to counter the red I see with the mark II when using any of the 709 LUTs.

That matrix was designed to match the C500 in 709, so it should be close.
