Nice shot. Love the mix of symmetry and asymmetry.
I completely understand about the fear, but there are a few things I believe and will share if I ever get challenged (which I haven't even once in three years) because I firmly believe in my reasons for doing what I do.
- I try to capture street life in its most natural form.
- I never shoot with the intention to make anyone look foolish
- I never take advantage of the homeless or sick, unless it's saying something particularly important
- If anyone still disagrees then I'll happily delete the picture and apologise.
Don't get me wrong, I'd feel bad if I got challenged but I would do my very best to get across the reasons for what I'm doing.
If you can be clear and believe in your approach then I'm sure you'll be fine. I like to think that people recognise genuine intent, and you certainly seem like a genuine guy. Can't wait to see some more street photography from you!
