The following two images of a coin have annoying blue edges. I was wondering if someone can explain how to get rid of them.
The picture was taken with a D70, a 70-300 lens and a 12mm extension tube. A glass-top coffee table was used. A 26 Watt daylight fluorecent bulb was lit underneath the glasstop, and a piece of regular sheet of white paper was placed on top of the glasstop. A 3-inch cylinder was placed on top of the paper sheet and finally the coin was mounted on top of the cylinder. The coin was lit with another 26 Watt daylight bulb screwed into a regular desk l&.
The camera was calibrated for White Balance. Another photo was taken with WB simly set to "daylight" and it had the same effect - a blue edge.
Thanks in advance to anyone who has some ideas about this annoying artifact.
