Brendan's post and the response bring up an interesting issue that seems to increasingly dominate the digital photography world--pixel peeping and hunting for defects. It is easy to zoom up to 200% and tear apart an image, but how much of the defects we observe will actually show up in real world applications?
For example, the DPReview Pentax SLR forum has had several VPN (vertical pattern noise) threads lately. Basically, if you crank the ISO way up, shoot in very low light, then amplify the shadow areas in Photoshop you'll see patterns in the noise. My *ist-Ds does it, but I never noticed it until I went looking for it. My ultimate conclusion is, "So what?" It's like the old joke where the patient says, "Doctor, it hurts when I do XXXX," and the doctor responds, "So don't do XXXX". I know that blooming and CA can be pretty obvious in certain situations (e.g., backlit tree branches in winter). In less contrasty cases, you may be able to find it if you go looking for it. If it's not obtrusive, however, why worry so much about it? Just a thought.... -- PDML Pentax-Discuss Mail List [EMAIL PROTECTED] http://pdml.net/mailman/listinfo/pdml_pdml.net
