>>4128259give the guy $5, its good to be a little charitable.
then tell him there's another $5 if you can photograph him for five minutes. don't say "a picture" or "a few photos" just say five minutes. if he says no then he's just greedy, so walk.
>>4128263>spend weeks getting to know them>shooting photos of people at their most vulnerableanon your heart is definitely in the right place and you sound like a good guy to know, but eventually you may experience that vulnerable animals are the most selfish of them all, and humans are no exception.
please don't advise people to hang around bums. most of the time, they've been identified as a danger to their past family/friends. you don't want to be their friends, nor their family. you just want a fuckin photograph, so offer the guy $5 and both of your days can get a little bit better without LARPing as some weird old photographer bitch.
