Eric Kim over at EK Street Photography Blog put together a nice video where he covers shooting with the XT-1 and X100s as well as (more importantly) some tips on how to approach strangers and feel comfortable doing so. It’s worth a watch and you should check out his blog.
I especially like his comment about asking strangers to take their photograph is still Street Photography. There is no hard and fast rule that says you have to sneak up on everyone you photograph
and steal their soul without asking… To each his or her own.
