Some years before C100...

This year we celebrate sixtieth anniversary of the beginning of the Czech television broadcast. Thanks to one enthusiasts (on the picture below) one a very old TV camera started to work again.

These screenshots are pretty useless as a comparison, beside being small there is no common factor that links them to make a comparison.

Look for color shift, it is very easy to see some color differences (orange-red, brown-yellow/green) on drapes in the background of scene. Sharpness or dynamic range is not the problem in this case of shooting. The big versions of pictures you will find via links.

I have no problem did some color correction with different cameras, but in this case I must used a secondery color correction. That's all.

Re: C100 vs. XDCAM EX vs JVC GYHD201 screenshots

Pavel,
I have had similar issues when doing multi camera shoots using different model cameras. It seems that the blue colors of the cameras are interpreted differently. Once camera shifts the blues more toward purple. When I try to correct it back to blue, it shifts other colors and messes with skin tones. I have to turn around a particular project in a hurry and I'd love to hear what kind of secondary color correction you performed to get the colors to match without messing up the other colors. I need to apply this to a nearly 2 hour clip so I am hoping there is an easy tweak that can save all of it.

Thanks if you can help out!

Re: C100 vs. XDCAM EX vs JVC GYHD201 screenshots

Hi Marty.
I don't have problem with blue or magenta color (some differences at pictures above are about the angle of view or color saturation). The biggest problem was green/yellow versus brown on drapes at background. I try to make a secondary col. corr. on the C100 but I got a wrong result (faces go with brown drapes...).
So I must made a secondary cc on XDCAM EX and JVC, where I can mask the saturated green/yellow drapes and turn them a little to the brown .-) .

Another secondary color correction I did on the red-orange dress. I made a less orange dress on the C100 footages. It is not perfect but it is ok for my purpose (pictures above aren't color corrected with secondary).

I do some test with C100 color now, I try different exposures and look for result on the color table. There I find that cine1 gamma has a best color for me (no big problem with blue, magenta or green color), WDR or canon-log are much worse with blue or cyan colors (and yellow). So I shoot with cine1 gamma and I will try to get the right colors directly from C100 - it needs some time for tweaking of the CP setting.

Thanks to last shooting (above screen) I have some idea what can be wrong. I'm not scientist, I only needs some acceptable settings for common multi-camera shoot.

So I hope that this help to you (I hope that you understand to my english).

(I work in Avid Symphony 6.5 where is the color correction section with secondary c.c. included. You can use third party plugins - correct selected color, BCC for example).
