    Hoping someone can help me out here as I'm using the Photoshop
    Evaluation version to edit some pics and evaluate Photoshop but for the
    life of me I can't get a decent red eye cleaned up. I'm using the Color
    Replacement tool as is suggested in the Help file with the following
    settings:

    Mode: Color
    Sampling: Once
    Limits: Discontiguous
    Tolerance: Varied from 30-50%
    Anti-aliased on
    For the most part, the parts of the eye I want changed get changed but
    the color is wrong. I can set the foreground color to pure black but the
    color that gets put in is grey. If I select other colors (blue for
    example), they go in fine. This has been driving me nuts as I've been
    trying to decide which photo program to switch to and so far I like
    Photoshop but this is the one thing I can't get working. I've been using
    Microsoft PhotoDraw for a while but have been looking at Photoshop,
    PaintShop Pro and GIMP.

    TIA
    Don

    Hi Don,
    Try these and see what you think:


    Red-eye removal:

    Use marquee tool (or your fav selection tool) to highlight the pupil. Open
    your channels palette, and select the green channel. Ctrl + C (PC) to copy
    green. Select the red channel and Ctrl + V to paste green channel to red.
    Select the RGB channel and deselect marquee.


    Red-eye removal:

    1.Make a Channel mixer adjustment layer and set the Red channel to Red 0%,
    Green 50%, Blue 50%. Don't get scared you'll get a completely off color
    image.

    2.Now select the mask of the adjustment layer and fill it with black by
    pressing Alt-Backspace. As the last step select the paint brush and paint on
    the mask with white to reveal the effect of the adjustment layer. Select the
    paint brush the size of the red spot in the eye.

    You could try this too:

    Set the foreground colour to black, select the colour replacement tool -
    under the healing brush in the toolbox, click on the red area in the eyes,
    and then paint it away - the brush snaps to the red colour - out of interest
    move your cursor over the tool's icon in the Toolbox, the eye in the icon
    changes to red.

    This color replacement tool method is what I have tried and though my
    foreground color is black, the pupils are turning out grey and don't
    look right.

    It's quite difficult to get rid of red eye, as just removing the colour
    leaves a rather strange looking eye.
    if you have a pic without red eye cut the eyes from it and paste in the
    images where you have the problem, they don't even need to be that persons
    eyes, anyones eyes will do you just have to change the colour.

    You'll get a number of useful suggestions for removing red-eye. Actually,
    you're on the right track already. This is why you're getting frustrating
    results just now. . . .

    You have properly set your options correctly, especially with the blend mode
    set to Color. This mode preserves the *tonal* variations of your image as
    you replace the colors. However, by intent, it does NOT effect the
    *luminosity* of the pixels you are correcting. That's why you get a variety
    of grays instead of a black. PS is preserving the luminance of the replaced
    pixels and replacing only the hue and saturation. The only way the Color
    Replacement tool could result in a black pixel would be if it were replacing
    an already black pixel (that is, the pixel already had a zero luminosity).

    If you're trying to replace red-eye in the pupil, just use the brush tool
    with the foreground color set to black. That works for the pupil because
    it's presumed to be a solid black anyway, with no tonal variations, so you
    don't mind painting with a flat black..

    If the red-eye splashes over into the iris, then go back to the Color
    Replacement tool and do you what you're doing now. However, add one more
    step by repeating the procedure and setting your blend mode to luminance.
    The first swipe replaces the hue and saturation of the red pixels with
    various shades of gray, while the second replaces luminance of those gray
    pixels with the luminance of your foreground color (black, zero).
    Effectively, you're painting the carefully selected pixels ("once" option),
    and *only* the selected pixels, with a solid black.

    There are a number of other to get rid of Red Eye but your approach is just
    fine and will eventually lead you to further understanding of the wondermous
    Color Replacement tool.

    Good question!
    Good luck!

    Try this:

    How To Remove Red Eye:

    Select Layer, Adjustment Layer, Channel Mixer.

    Set Red to 0%, Blue and Green to 50%. It’s going to look off color.

    Select the Mask of the Adjustment layer and fill it with black by
    hitting Alt-Backspace.

    Paint the mask to reveal the color under the red eye.

    The Sponge to suck the red out. And some Burn tool if it got too bright.
    Simple and effective.

    I like red eye removal tool in PhotoShop Elements 3.0. You chose the tool
    and there are two options; one is pupil size and the other is darken amount
    both in percentage. You just click inside the red pupil and it does an
    excellent job.

    May be Adobe in their next version of CS should implement some of nice
    features of PhotoShop Elements!!

    You can download trial version of Elements 3.0 and give it a try.

    I use a red-eye plugin from another Adobe prog. Very easy, quick and a good
    result. Just put a rectangular marquee around the eyes and click on the
    plugin. I'll email it if you desire.

    Unless it does it as well as current techniques it's just another bit
    of marketing bling.

    Ya thanks I have already done that and I agree it's lot easier (and
    works well), than CS.
