Quote:Ok, Ive got a bit of a pickle. In looking through my pics on my camera card I cant remember what was inside or outside of focusIam "pretty" sure these first two pictures are OUTSIDE focusInside (pretty sure) focus and its not a good quality shotSo if my inside/outside focus is correct I think she is under corrected with maybe a turned down edge
Quote: His really dark image is supposedly inside focus.
