    I would greatly appreciate your help on the following question.

    I have some portrait pictures with shadow on the wall (background)
    caused by the camera flash. I would like to remove the shadows.

    While searching in this group and on internet, I understand that there
    are various methods to get rid of shadow.

    I understand that removing shadows using channels is one of the good
    methods. Could you please explain this method?

    Here's what I found on internet - but not sure how to do it.

    "there is a method using CHANNELS to exactly match a discouloured
    portion of an image to its surrounds. it is primarily used to remove
    stains such as wine stains from photos, but i have used the technique
    many times to remove shadows from portrait shots, matching the skin
    tones in the shadows to those surrounding the shadowed portion. i dont
    have enough internet time at the moment (not on my computer) to go
    through the entire technique, but a cursory search of tutorials on the
    net should help you find the technique, as it has been shared by the
    adobe programmers. the critical point being, that channels are used to
    correct this, not burning or dodging or contrast masks or anything
    else, which will give u sub-standard results compared to the channels

    Why not put up a copy of the image and see what people will do with it. We
    love a challenge.

    Meantime, apologizing for my brevity, this may be helpful: using a contrast
    enhanced copy of the "a" or "b" channel from Lab mode as a selection or
    layer mask may save work in either cloning out the shadows or using curves
    to lighten the background generally. This will be most effective if the
    wall color differs from the people or objects that are casting the shadow:
