Saturday Night on Mill Avenue in Tempe AZ.
While I took a knee to get a great angle this street performer walked over to me, grabbed & covered my lens and scolded me, I was surprised at his action and after my personal space, property and person were violated I backed up took aim and continued shooting.
No, I don't tip before I shoot :-(
From my point of view it would feel like cheating by paying for an image and that would take all of the sport out of what I call street photography. My approach is professional and confident with a sincere interest in the subject. I am not on the hunt for aggression but I do enjoy the reward of real emotion in an image. I don't provoke or instigate, as that too would be poor sportsmanship.
Looking at this image reminded me of the famous Johnny Cash "Flipping the bird" image.
