I have always been intrigued by people, and in my work (not photography), I get a lot of opportunities to travel.
To discuss - Its easy to "steal" a shot of people with real expressions with telephoto lenses, but what about moving up to subjects closer? (Without getting k-ed by anyone of course, since they are strangers afterall).
What are things you have done in the past? Human beings on the streets makes a wonderful subject to shoot, like the old homeless man shifting through garbage on the streets of Hong Kong to a cobbler in China, these are great subjects. Move them into a studio/controlled lighting environment and everything is lost.
Any tips that you can share?
