Honest question: Recently I took a 6 weeks vacation. One of my cameras had a dust particle that resulted in several thousand pics having a semi translucent watermark-like impression. I think that the process shown here to defeat those watermarks would be ideal to batch-correct my pictures. (As of now, I have to manually correct the ones I love and leave the others as they are). Does anyone happen to know a tool that would allow me to do something like that? As I remember, the same thing happened in one of my friend's wedding. The photographer they hired had one of his lenses with dust, spoiling a lot of pictures... It would be a really nice tool for those situations if they release that code.
