Matching camera colors in Premire

Hello, i shot a concert using 4 BMCC 2.5K and two BMPC 4K. I am editing in premiere, the colors from the 2.5K cameras is very different form the colors in the 4K camaras. Some forum members told me about a good solution to this problem in Da Vinci Resolve, but I can´t use Resolve in my 2007 Imac, I tried every possible way. I can only use Premiere CS6, is there a way I can match the colors as much as possible?

Isfthere is not a direct way to do this, what parameters or effects should I try to adjust? I dont have much experience in colorimetry



These are 2 examples, I only did some RGB curve correction. In the 4K skin tones are darker , the guitar is medium brown. It can look really weird in the editing.

How would you approach this correction? I mean what parameters or colors should I touch in the 3 way corrector, what´s the way t go more brown?

So fix that. First thing you do is get yourself a copy of the Color Correction Handbook by Van Hurkman. Read it, it's an easy read. It'll tell you what you need to know about how colors interact, how colors interact with luminosity (aka value, exposure, lightness, etc.) so you'll know that brown is just dark orange. It'll tell you how and when to use a waveform monitor, a vectorscope, and how to use an RGB parade to identify and correct a color cast. And much much more. All stuff you need to know to do a good job color correcting.

As to PPro CS6, the big tool available for this duty is the three-way color correction tool. It's actually quite good for what it is. You'll need to read up on it and learn it. Good place to start is perhaps the Andrew Devis tutorial on it over at CreativeCOW.

If your delivery for this project is the Internet, you can probably get away with color correcting on a computer monitor. Calibrated monitors give better results of course. If your delivery is HDTV (include DVD, Blu-ray, broadcast, etc.) then you'll need a monitor that can show you your footage in the Rec.709 color space. This is typically a calibrated production monitor, but can be something as basic as a calibrated HDTV. Without this, you'll have to iterate: make your color corrections, render the footage, burn a DVD, take the DVD to a DVD player hooked to an HDTV, play the DVD, take notes, go back to the computer, make more corrections, burn another DVD, ... repeat until done.
 
Is not much of the problem exposure rather than clout? The guitar is just the real colour but not the same level as the other?
 
Thanks, I will read that book and the tutorials. I think is a color problem, I tried exposure and saturation.
