I have a few hundred scanned slides that are about 30 yrs old and contain quiet a lot of dust/scratches.
I'd like to use a filter to automate removal of most dust/scratches as I cannot realistically do this manually on each photo.
Looking around I found that Polaroid did release a great filter for this purpose but I have not had a chance to try it out just yet.
What I'm looking for is a filter that can remove most of those defects and one that could be run in a batch. I'm flexible with either a Linux or a Windows solution.
To give you an idea of the pictures that I have to process, here is a sample.
