Time to fill in some pin holes. Anyone successfully retouching their negatives to turn those tiny clear dust spots into not-so-tiny gray or black blotches that are more amenable to spotting on prints? If so, what solution do you use? I remember reading a few years ago in an article by Huntington Witherill about a solution, not Spot Tone, which was then available. Can anyone point me to an article that gives current choices?
Thanks.

PS. I just got my new website up, and I would like feedback. If you like it, reply here. If not PM me.
