    In this picture[email protected]/191080542/, which
    is a 13% crop of an file that consists of 6 scanned and merged images there
    are lot of moldstains. It is a very old picture from my father in his study.
    I could remove these stains using the rubber stamp and/or gaussian blurring,
    but it is a LOT of work, since they are all over the picture.
    Is there a way to automate the process?

    Hi Rutger,

    I hardly ever post to any of these forums, but I was in here looking
    for something and came across your dilemma and thought I might be able
    to help.

    I don't know anything about how to automate a process for what you're
    trying to do, but I have used the Dust & Scratches filter with
    satisfactory results on some recent photos that had considerable mold
    stains and other surface blemishes. I downloaded your image and spent
    about 10-15 minutes on it just using this filter. You can see it here:[email protected]/191318450/

    It seems to work better in some places than others, so I used the Lasso
    tool to select and copy certain sections to their own layers. This way
    I could apply the filter to each section separately and adjust the
    parameters to get the best results. I started with the large area of
    wall at the top right, then moved onto the sleeve, his hand, various
    sections of the jacket, and then his face. About 5 or 6 layers I think.
    I didn't try to fix the whole image, just enough to give you an idea of
    what can be done with the Dust & Scratches filter.

    When you open it (under Filter>Noise), you'll see sliders for Radius
    and Threshold. Start with both at 0, then slide the Radius up until the
    blemishes disappear. (Make sure the "Preview" box is checked.) Much or
    all of the texture will disappear with them, but as you slide the
    Threshold up, the texture will return. Just don't go too far or the
    blemishes will return too. I found that having both sliders at around
    10 seemed to work on most of the sections, but not all, so play around
    with them. Like I said, it seems to work better in some places than
    others, so you'll probably still need to use the Clone tool for certain
    areas, but hopefully this will help. By the way I tend to use the Clone
    tool set alternatively to Darken and Lighten, rather than having it set
    to Normal.

    Good luck and I hope this was helpful :)

    I guess i have to thank you, but the picture you kindly processed is in a
    private area :-(.

    Whoa, really sorry about that :( I guess it didn't show up as
    "private" when I checked the link because I was already signed into
    Flickr at the time. I don't recall setting it that way, so it must do
    it by default or something. Anyway it's fixed now, please try again ;-)[email protected]/191318450/
