Street photography can focus on people and their behavior in public, thereby also recording people's history. This motivation entails having also to navigate or negotiate changing expectations and laws of privacy, security and property. In this respect the street photographer is similar to social documentary photographers or photojournalists who also work in public places, but with the aim of capturing newsworthy events; any of these photographers' images may capture people and property visible within or from public places. The existence of services like Google Street View, recording public space at a massive scale, and the burgeoning trend of self-photography (selfies), further complicate ethical issues reflected in attitudes to street photography.
