I know that one day search via facial recognition will be good enough for people to find these kinds of photos of themselves. Snapped candidly in public, without their knowledge.
I hope they don’t mind. I know I wouldn’t. I feel candid street photography goes a long way to creating a historical document.
I was always curious to see what I looked like when asleep so a few years back I went through a lot of trouble to get a photo. Setting up a tripod and timed release etc. It wasn’t all that amazing. Maybe one day I will try to capture sleep using some time lapse photography.
