>>4011625If a person is standing still or sitting down you ask them if you can take their picture.
If a person is walking you walk by them and take a photo quickly without asking.
In my country it is not illegal to take photos of people in public but it is illegal to breach someones privacy by releasing a photo of them publicly without their consent. So you have to be careful and prudent.
The worst case scenario is you take a photo of someone and they come up to you pissed off that you took a photo and ask you to delete the photo. I only shoot on film. So I explain this to them, which they usually don't understand. I give them my business card, exchange contact information and get them to write their details into my notebook where I write no consent, frame number, persons name, date, film type etc.
One day I will take a photo of someone without asking or rather I will take a photo of a scene and someone will come up to me pissed and probably call the cops. When that happens if I cannot come to a consensus with the person or potentially the cops, I will probably have to forgo an entire roll of film.
Also: Just don't take photos of children. For some reason every parent thinks that some stranger, especially a male stranger, that takes photos of kids is a pedofile. There is a double standard whereas women can get away with taking photos of children.
