Perhaps this is my own personal hangup, but when I'm out on the street and I see something I want to take a picture of, but it includes a person or people, I always feel weird about taking someone's picture without their consent. And if they notice me, I don't take the picture.
How do others get around this? Do you just take the shot and consent be damned? Or do you ask first?
I'm sure I've missed some great shots because of this.
