    Inconsistencies when using automatic colour

    Stacey Bindman Community Member

      Hello All,

       

      Can someone please explain the inconsistencies I am having with automatic color in CS6 updated on a Mac with OS Mountain (latest version)?

          1. A screen-capture of 4 separate images - they are in 4 separate layers

               The 5th layer of "Copyright Do Not Copy" does not affect automatic color!

          2. An entire working PS screencapture

        3. If I use Image >> Automatic Color on 1 layer at a time, the images go blue (cold)

      4. A second Image >> Automatic Color illustrating the cold automatic correction

        5.  a.  If I  Layer >> Merge Layers or Layers >>Flatten Image

              b. Image >> Automatic Color I get a slight color correction as I would expect.

        6. If I use the any of the identical images from the first image at the top then Image >>Automatic Color, it goes cold (Blue)

        If I keep all 4 images together without any white area between them or around them and then Image >>Automatic Color

        the correction again like # 5 is only a slight color correction.

       

      What I'd like someone to please explain to me is why the inconsistencies in Image >> Automatic Color in these different settings,but all of the same images

       

      Thanks,

          The images do contain different amounts of differently colored pixels and no reference bars. In some of them there is not even pure black I would suspect. The result is more or less to be expected - the algorithm tries to find some minimum, maximum and intermediate reference points per channel and then tries to even them out. It obviously works better with the white frame because that defines the maximum white point and may give a better midpoint reference in turn....
