To be more specific as time passed I’ve noticed a shift in the way I approach street photography, in the earlier days I’d be more open to photograph people on the streets and while I still do, I’ve adjusted to taking photos from more of a distance or ideally from angles where their faces aren’t directly in the frame. Feels a bit weird at times because you’d think that as you shoot more you get comfortable with these scenarios. Maybe it’s a form of growth to respect peoples personal space, a bit more but I also just prefer that look. I don’t think there is a right or wrong way to handle street photography but curious to hear what others have experienced over time.
Maybe there’s an also genuine - and justified - change in people’s concerns about how their photo will be used. Probably 99% of these photos are now taken with the intention of sharing them online in some form, so the potential for your image being used or exploited in a way you don’t like or approve of, and seen by many thousands of people, is hugely increased. That risk was just not the same in the 1960s and 70s.
Also there’s always been a surreptitious aspect to it and some photographers are just more comfortable with that than others - people were using concealed cameras to do candid photography in the 1930s.
