    Still looking for the perfect red-eye reduction process in Photoshop

    My grandson, shown at
    has very light-colored blue eyes. When I try to correct flash photos
    with red-eye, I can eliminate the red-eye but the result is eyes that
    are much darker than the real color. The process that I use works
    fine on situations with other subjects where the normal eye color is
    fairly dark, but not on the light-blue eyes.

    I've tried many different red-eye reduction methods, and currently use
    Lasso eye>Image>Apply Image>Channel: Green & Blending: Darken>OK to
    take the red-eye out of the lassoed selection. As I said, works OK
    for dark eyes, but not for the light-blue eyes.


    BTW: That's chocolate birthday cake smeared all over him. Not what
    you might have thought.

    Hi Tony,

    Perhaps you could point us to a photo of your grandson with red-eye and we
    could try and come up with a solution that would work for you.

    that's why I love ambient daylight for portraits better
    as the example you show
    but if you want flash portraits do not use the pop up one from the camera
    But if you have to buy the little diffuser thingy that goes over it (I have
    tried a rubber band and white tissue works in a pinch
    does you camera not have the red eye reduction feature??
    we use strobes that do not make red eye

    to fix red eye you may have better luck using desaturate rather than cloning
    or painting in a color

    Sure. The image at
    contains two cropped down photos that both have serious red-eye. I
    can correct the younger grandson's red-eye because he has dark brown
    eyes. When I correct the older grandson's red-eye, his eyes come out
    much darker than his eyes are in daylight pictures:

    Here's my attempt to correct the red-eye in the lower picture:

    There's too much red fringe left, but this attempt isn't as bad as
    some. I had enough blue iris unaffected by the flash to show some
    blue. Just the pupil was affected. On this, I used Image>Image
    Adjustments>Green Channel& Darken on the selected area.

    Using the Selection method, it's really hard for me not to leave a red
    fringe as seen in this image.

    Not to sound unappreciative of comments offered, but I *do* know
    ambient light and daylight is better than flash. The thing is, you
    sometimes have a shot where flash is the only option. Most of the
    holiday shots will be indoor shots.

    I don't do portraits. I do candids. With two little kids running
    around the house, setting up external lighting is just not practical.
    It might be if I *was* going for a portrait, but not to shoot just pix
    that are taken as part of the regular evening.
    Before I posted the first time, I tried some on-line tutorials. The
    one using desaturate came out with eyes as flat and gray as a shark's

    I haven't tried diffusing the flash as you mention. Sometimes I'll
    force the flash not to fire, get a too-dark image, and correct with

    My real point is that when you do have a good photo over-all, but
    there's red-eye, how to go about correcting it.

    Zoom in on the red eye, click on the red channel in the channel palette, and
    paint the iris of the red channel black. If there is a catchlight it will
    turn cyan, which is usually OK. You can fix it by painting it white again
    with a smaller brush.

    If you are using Elements, set the foreground color to cyan RGB(0,255,255),
    and set the brush mode to multiply to blacken the red channel.

    Hi Tony

    I think you have your attempt about right!! the 'red eye' is actually on the
    black part of the eye (the pupil) the blue part is not reflective and does
    not change to red!!

    That attempt is good enough, if it were for me, but you must have an eye
    of a hawk! If you further want to reduce red fringe, can you not sample
    the red fringe with the colour range, and desaturate the selection? And
    level appropriate channel in the blue eye area afterwards to match?
    Don't know how clear the original image is, so hard to say, but HTH.

  9. Try this;

    Zoom in on the eyes so they are big enough.

    Press "Q" to enter Quick Mask.

    Press "B" to select Brush tool.

    Paint the pupil/red area with brush at 100%.

    Press "Q" to exit Quick Mask.

    Press Shift+Ctrl+I to invert the selection.

    Go to Channels palette.

    Go to the Blue Channel and Ctrl+C to copy the selection from just that

    Go to the Red Channel and Ctrl+V to paste from the Blue.

    Go to the Green Channel and Ctrl+C

    Go to the Red Channel and Ctrl+V.

    Ctrl+D to deselect.

    I rather do everything using CS2, however, when I have to reduce red eyes I
    use IrfanView.
    The final effect is much natural than in CS2.

    Granny typed:
    I personally hate the red eye reduction on the camera.. there is already
    way to much lag time. Sooo.. I get a lot of red eye when I use the on
    camera flash..

    The following method works well for me and eliminates the flat like a
    shark's eyes look.

    First Ctrl+J to copy the original layer then I go to the layers menu and
    uncheck the original eyeball.

    Zoom to 600% or 800% on an eye

    Go into quick mask by pressing Q on the keyboard.

    Paint the entire eyeball including the whites with a small brush.(paint
    within the lines)

    Repeat for the other eyes... I even do the teeth (Just make sure you
    have a hard brush and avoid the gums..paint within the lines)

    Get out of quick mask mode by pressing Q again.. that should show all
    your selections

    Invert the selection by pressing Shift+Ctrl+I

    Go to Image, adjustments, Hue/Saturation.

    Press Ctrl+1(brings up "Reds" in the edit box)

    Using the saturation slider .. slide it all the way to the left ( this
    gets rid of the red) and leaves the other colors alone)

    Using the lightness slider move it to the left to about -40 or till an
    eye looks right to you

    Sometimes I have a magenta hue left that is noticeable,.... Like in the
    little ones eyes in the orange shirt in your picture,.. just press
    Ctrl+6 to edit the magenta and using the saturation slider again move it
    to the far left... then lighten if needed.

    The next step helps clean the teeth and the whites of the eyes a
    little.. press Ctrl+2 to edit the yellows.. use the lightness slider and
    move to the right until the teeth look good.

    Press OK in the Hue/Saturation popup.

    Press Ctrl+D to deselect your selections.

    Double click the Zoom tool to get back to 100%.. check out the magic

    I save as... using an appended "A" to the original file name, thus
    leaving my original untouched

    Believe me, it is a lot faster to do than to try and explain

  12. And, believe me, it's worth learning how to avoid this in the first
    place. It starts with using a dedicated flash unit, bouncing if
    possible, and keeping as far away from the lens as practical.
    John McWilliams, Dec 9, 2006
  13. That's a rather pointless exercise. First you paste the blue channel
    into the red channel, but then you undo that by pasting the green
    channel into the red channel as well, which will replace what you just
    pasted from the blue channel.

    You should copy the darkest channel, and paste that into BOTH other
    channels. That will make the eye dark and neutral.

    That's entirely beside the point. The question was not "How do I
    prevent red-eye?", but "How do I correct red-eye?".

    I have three cameras, but only one with a hot shoe for flash. I have
    external lights that I can set up to eliminate the need for flash.
    Either can be used for posed pictures.

    Sometimes, though, a candid opportunity comes up where the first
    available camera is grabbed, and the resulting picture includes a bad
    case of red-eye. Rather than scrap the opportunity or the photo,
    knowing the best way to correct the problem is essential.

    From someone who is still very much a learner and quoting what is said
    in 'the book'

    1. Using zoom tool drag a marquee around the eyes to zoom into them.

    2. Select red eye tool hidden under the spot healing brush

    3. On the tool options bar leave the pupil size set to 50%, (OK maybe
    whatever you are working in) but change the darken amount to 10%
    Darken specifies how dark the pupil should be. Because the child's
    eyes are blue, we want the darken amount setting to be lighter than
    the default.

    4. Click on the red area in the boy's left eye, then click the red
    area in his right. The red retinal reflection disappears.

    Hope that helps....

  16. The question was already answered. My "besides the point" point was just
    that: an additional point.
    Wasn't suggesting anyone forgo an opportunity for lack of perfect setup.

    This works for me.
    1. Add a channel mixer adjustment layer
    2. Set red to 0, blue to 50 and green to 50
    3. Fill the adjustment layer mask with black
    4 With a brush approximately the size of the red spot, paint
    with white on the pupil. If it runs over a little it is not

    Hope it works.

    Thanks to all who replied to this, including those that replied by
    e-mail. I've tried all the suggestions.

    To my eye, the Irfanview red-eye reduction process is the simplest to
    use and the results are close enough to being equal to the results of
    the more complex processes that require more steps. There might be
    individual pictures where the more complex processes would work
    better, but not in the images I've worked on.

    Somewhere along the line my post was trimmed. I use Photoshop 7 which
    does not have a red-eye tool. I think that's a feature added in CS2.
