When you first caught sight of this picture did you see it as the woman on the left lifting the man next to her by his jacket?
I can't help seeing it whenever I look at this picture quickly. I'm not going to pretend that I saw it at the time and shot it intentionally. Maybe it registered subconsciously and caused me to release the shutter at that precise moment. But if I'm being honest it was probably just a happy accident. I did however, see it straight away when I was later editing the day's images and making my selects.
Street photography relies on this kind of trick quite a lot. And I often wonder how many famous photos from the masters of the genre were intentional and how many were discovered later, when looking through the contact sheets.
