I took a picture of an oil painting. I have two softboxes at about 45 degrees. On the picture I get tiny bright white spots, caused by relief in the paint. I tried changing the position of the lights, but that removes some reflections and gives me other reflections in return. I tried removing the spots with gimp, but I couldn't get it right.
In another question I read that a polarization filter helps. I'll try that. Is there anything else I can do?
