DP2M macro moire?
I'm a new Sigma owner and am enjoying my DP2M very much. However I sometimes see an image artifact that is annoying: an alternation of red, green and yellow(?) that doesn't exist in the original subject. Below is an image processed heavily in SPP, and below that is a crop that exhibits the phenomenon (look at the vertical 'columns' in the crop). Anyone know what's going on or what I'm doing wrong? Thanks for looking.
