I'm loving this thread, because it's relevant on so many levels: equipment, technique, being affable, confidence in one's work.... I'll just add an experience of my own. Just an anecdote for your enjoyment. FYI, I have been shooting w/ a Canon EOS-1N with a large motordrive, which as you may know is a huge piece of gear. Even w/ a "pancake" lens, this thing is not unobtrusive. (I only recently picked up an RF, so I expect that I'll be able to be a little more subtle in the future.) Perhaps because I live and travel in largely cynical, metropolitan areas, my experience with subjects has been full of hostility, even though I try to act w/ confidence.
Anyway, at a Christmas parade last weekend (Solvang, CA), in the last 50ft. of the route a woman stepped out to get a photo of Santa in the sleigh and got run over by the "sleigh" float. The parade came to an immediate halt and "Santa" and "Mrs. Claus" were looking over the back of the sleigh at the crumpled woman on the ground. Looked like a great shot to me, so I angled in w/ my massive gear (20-35mm lens, BTW) and a 60-ish year old "elf" started getting nasty. "We don't need any pictures here," he said as he menaced me. He pushed me aside and stood in my way with his hands on his hips. I tried taking a picture of this 2-meter tall elf with a nasty look on his face, but he put his hand over my lens each time. I got so mad ... but there's little to do in that situation, I guess. I don't want to get into a shoving match over taking street photos.
Any other real-life experiences out there?
