using blending modes to see dust spots better?

[Morgan Collini]

I once saw tip for dusting that copied a layer and altered the blending mode so that the dust specks were highly visible, and then you use the clone stamp BUT I haven't been able to remember it or reproduce it...little help here?!?

Depending on the specks and the photo, I've been able to amplify the appearance of dust using multiply, dodge, and burn. However, I generally use a curve adjustment layer instead for that sort of thing--just crank in a steep curve to accentuate the contrast between the dust and the subject. Then the dust disappears as you work.

Have you ever tried the Polaroid dust/scratch remover? It is a free download filter that I have obtained recently...lets you isolate light and dark particles and adjust level sliders accordingly. I like to select eyes and mouth and then select >inverse so that it runs on everything but that. Sometimes if you have a lot of dirt it accidentally removes catchlights from eyes. Just a thought... might help if you have regular dust issues.
