well, sometimes, pixel peeping is necessary. If you intend to print large, you should definitely pixel peep. There might be a stray object, dust in your lens, or whatever. You might find those on a larger print and discard your print after the fact.... I've done it multiple times now since I tend to avoid peeping.
Nowadays, pretty all of my landscape photos are peeped. It's just my personal belief in clean technical work.
I get it for landscape photos that are being enlarged to 20 x 30. And you're right - I think even Ansel Adams scrutinized his photos on his enlarger before he made a print. So I know you do have to mind clone stamping out people, burning and dodging in the right places, and otherwise cleaning up big landscape enlargements.
Peter Miller was just mocking the people who pixel peep on every one of their photos and then start to debate the merits of a 24-70 f/2.8 versus a 24-105 f/4 versus a 50mm f/1.2 prime because they're sitting around on their computer pixel peeping at every image trying to prove to themselves which lens is inferior. He was saying that's stupid and a waste of time. And he's a millionaire producing photographer. So I think he's on to something. Hehehe
