hehehe, I'm sure there could be a few santa's out there that took the job for the opportunity to be close to children (be it a good or a bad thing).
I am disappointed with myself, and my failure to inform the santa photog of these forums. Perhaps I'll head back there tomorrow and see if the same guy is around and strict up a conversation with him.
I simply handed him my camera, it was set to f/16 or something as I was shooting outdoorsy shots just prior, and he selected f/8 and zoomed the kit lens to around 50mm - which is what you see here, everything rendered pretty sharp. Noting that he chose the sweet spot of the lens, both in terms of zoom and aperture selected, I get the feeling this guy has a fair idea of what he's doing... and should be beyond taking santa photos for kids.
As for my physical appearance - yeah, I should have put more thought into preparation. Shave, take off the sunnies, etc.
