Street photography is generally seen as unposed and candid, but there are a few street photographers who will interact with strangers on the streets and take their portraits. Street portraits are classified as portraits taken of strangers in the moment while out doing street photography. They are seen as posed though because there is interaction with the subject.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.
