The European Union and the UK are tightening the rules on what is permitted in shooting images of random people. And the concern of parents is common here and there. I love shooting people living their lives and the kids in the neighborhood are part of it.
For instance, a pick-up ball game in a little square on the canary Islands, I got blasted by a mom for shooting pictures of the game, but I was fairly certain I caught the flack because two other tourists off cruise ships had been asking kids to pose for them a few moments earlier and word must have gotten to Mom about that. My shots all had the ball in action.
In Hyde Park, I wanted to shoot the memorial to Princess Di, but there were so many half-naked kids playing in the water I never raised my camera, nothing I could safely shoot. A short distance away there was the Peter Pan statue and it was virtually always covered by climbing kids. I got one shot with no faces visible and only after making sure that parents standing by were comfortable with me shooting.
In Holland I saw an older toddler playing with cars at the open air cafe at a museum. The floor was white tiles with lines of black tile and the kid was pretending the black tiles were streets. Cute image, but I had to explain to a father that I was only shooting it for the composition and that the picture wouldn't be used commercially.
Not many year before, when I was working for a paper, the editor could say, go get a picture of kids playing in the pond. Or, go find a snowball fight. Or , see if any kids are skipping school and jumping off the old bridge. Seasonal shots that everyone enjoyed and no one thought ill of. Those days are gone forever, I guess.
