I understand that street photography is mostly candid shots. I guess it’s the “sneaky,” dare I say “under-handed,” ways to take shots that put me off.
In Central America, residents are more protective of their privacy. I deleted images by request and was very respectful to get permission to snap close-ups of children. Some people feel that you are trying to take part of their soul. No casual street photo, to me, is worth seeing someone become distressed over it.
Also, under some circumstances, with commercial interests involved, a street photographer cannot do with it as they please. (Ask actress Katherine Heigl.)

that’s literally what street photography is – taking photos of people in their most natural moments. if it’s a public place, a photographer has every right to take someone’s photo and cannot legally be forced to delete the photo. it’s their copyrighted property and they can do with it what they please. generally, if we take a photo of someone and they ask us to delete it, if it’s unimportant then we will, but otherwise we reserve every right to keep that photo of that lady walking her dog across the street.
