    2 cam color balance

    2 cam color balance
    I've been a shooter now for some time with my XL1 and XL2 and everything has come together except now. I'm beginning some projects requiring a 2 cam shoot. When we reviewed our video from the test shoot, the 2 cams color did not match.

    I had white balanced each cam with a white card manually. We used 2 pro lighting setups so light was not an issue. However, i feel that my error in balancing the 2 cams was not in using the same Fstop and shutter speeds.
    Any help? Deadlines are approaching and I'm desperate to have my theory confirmed or and alternate suggestion.

    Thanks everyone in advance. This forum site rocks !

    That could do it, as well as camera placement during white balancing and possibly the position of the white card changing. Note that some cameras will not match up with others no matter how much you try

    I had not considered the placement nor distance needing to be equal when balancing with the white card. duh. I'll give it a try when making my next test shoot. We really love our Canon videocams but there seems to be these hoops that need to be jumped thru from time to time.
    I really appreciate your input and advise and am grateful for your assistance.
    Thanx again,

    make sure the card is the same distance, and the lighting is the same (light meeter) Then when it is still not right.....Usualy is not perfect.....you will need to adjust in post. Black balanceing is a good idea too (not all cameras will do it)

    Usually simply placing the white card and not moving it, keeping the cameras in somewhat standard positions, and white balancing them both on the hottest white you can see will do it.

    on the otherhand i just thought of this......If you are using 2 diffrent cameras (even made by the same Company) there is almost a %100 chance that you will have to use a color corrector in post. the cameras probably use 2 diffrent lenses and the computers in them are diffrent!

    I use top have this problem when i was running my old cameras. Since i Bought my JVC HD cams (3 of them) the colors match up fine every time
