Secret photography

Secret photography refers to the use of an image or video recording device to photograph or film a person who is unaware that they are being intentionally photographed or filmed. It is sometimes called covert photography, a term used mostly among professional investigators, or unauthorized photography.

A person may be unaware of being photographed in a variety of situations, such as:

Sometimes normal cameras are used, but the photographer is concealed. Sometimes the camera itself is disguised or concealed. Some obvious element of concealment (or great distance) is generally needed to make such photography fall under the category of 'secret photography' rather than street photography or documentary photography.
