I have been taking pictures in public places, at events and weddings and in the "public eye" professionally and recreationally for a very long- lone time. Seems to me that most folks are polite and friendly. Usually people just let me go about my business without interruption. Even in a public parks, the zoo or on the street, I find that most folks will not walk in front of me when I am getting ready to shoot. Occasionally someone will com over, inquire about my gear and I am always kind and polite. People who are seriously interested in photography may engage me an a conversation and if I am not crazy busy, in the midst of an assignemnt, I certainty don't mind stopping for a chat.
In my own situation, I am a local business operator- I have a studio and good public relations is important to me. I always hand out business cards and quickly tell folks what I do. I have actually met some of my best clients "on the street"!
I have shown up in places with everything from an 8x10 view camera to 35mm equipment. My old film SLRs were so worn out a beaten up, I don't remember anyone being impressed with any of that old stuff. One bystander asked me where I got the "golden' camera- all the black finish was worn off and the brass was shinning through!
I never get aggravated when folks say that I have a good camera that takes good pictures or that I take good pictures because I have a good camera. As long as they know I take GOOD pictures, my answers is "YOU BET- I can take some good pictures- of you! Oh- they gotta pay me a lot of money too!
What's with will all this resentment of folks with cell phone cameras- good for them! I'm for anyone who likes to take pictures and have fun! It's a good way for kids to get acquainted with photography- the talented ones will advance to better gear if they are encouraged and inspired.
I was never an "equipment" snob". We all know, those of us who know our craft, that good photographer make good pictures- good camera just make it more fun and a bit more convenient.
Magic words for getting along with folks when shooting are PLEASE, THANKS, EXCUSE ME- some folks are surprised on how far those word can get you!
Oh, ain't nobody ever tried to rip of my gear- perhaps because I am big and kinda ugly! Age has endowed me with bad case of perma-frown, but I try to smile as much as I can!
