Yesterday while taking some macro photos of my corals in my reef tank I noticed a red spot on each photo when I zoomed the picture. The spot is in the exact spot on each photo and is bright orange! Unfortunately I bought this camera at Circuit City but did buy the perfmance plan which covers wear and tear, but can this be fixed? The camera is a Nikon D40 and is only 3 months old...... Any info would be great or suggestions... Thanks S.
