can photoshop apply the characteristics of one histogram to another?

Discussion in 'Photoshop Tutorials' started by Jacob Jackson, Sep 23, 2003.

  1. Ok, another question folks, if you don't mind...
    In looking at my RGB histograms, it would be a lot easier for me to simply
    apply the characteristics (the same curves in other words) of one of the
    good histograms to another. So, since my red channel is best, could I
    simply apply the same curve to the blue channel and if so, how?

    Thanks, once again,
    JJ

  3. Hi Yusuf,

    Thanks for the suggestion. I've used the channel mixer before, but not in
    this way. I'll have to try it.

    Thanks again,

    Wouldn't pasting the red channel in to the blue give the same histogram?

  5. Yusuf,

    It worked! By reducing the blue and boosting the green in the blue channel
    with the mixer, I was able to stretch out and flatten the blue peak! The
    resulting RGB looks a lot better now and, most important, no more bluish
    cast!

    Thanks again for this valuable info!

    Best,
    JJ

  6. Yusuf was correct. The remixing in the channel mixer, before doing any
    other processing, has solved my bluish cast problem.

    Thanks for your suggestion though.....

    This is the sort of problem that is often easier to fix by using
    Image->Adjust->Curves.

    Hi,

    Yes, curves was the first thing I tried, but it wasn't getting me anywhere
    (of course I am inexperienced). I still couldn't get the peak flattened and
    spread out as well as the remix of the blue channel in the channel mixer
    does.
