Chris, There are many caveats. For instance you aren’t allowed to make a blameless woman look like a streetwalker. Plenty more like that one about cheating people. But, generally, if you’re on public property – say the street – you can shoot any damn thing you can see, unless you’re violating the privacy of somebody who has an expectation of privacy, or unless you’re shooting something like military secrets. Someone who has an expectation of privacy would be, for instance, somebody looking out the window of her home. Of course, if you’re on somebody’s property, that’s a different story. The owner of the property can keep you from shooting pictures. Bert Krages covers the subject in reasonable detail in his single-sheet PDF (carry it in your pocket) to which I referred earlier. He also has a book: Legal Handbook for Photographers, which you can get from Amazon for ten bucks. Bert’s a photographer as well as an attorney, and he’s an authority on the subject of photography law.
