If you're taking a photo of a bum as you so eloquently put it- speak to them, find out why they are there- connect with your subject and then capture the emotion as you notice it.

If you are taking pictures of people on the street you are bound to get people fired up. Search YouTube for street shots Bruce Gilden. You will see what I mean.
Bruce Gilden, That was really interesting. Don't think I'll ever do what he does. I mean being a photographer myself if he come up and does that to me with a flash on the street even myself will punch him in his face, haha... Interesting character.
