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.
It has been in use by British police since intelligence gathering on the suffragette movement in the 1900s.[1] Some classic early U.S. street photography - such as that of Paul Strand on the Lower East Side[2] - was obtained by fixing a second "dummy lens" to the camera, whereas the real shot was taken from the side. Although spy cameras small enough to fit inside a pocket watch had existed since the 1880s, since the 1950s advances in miniaturisation and electronics has greatly aided the ability to conceal miniature cameras, and the quality and affordability of tiny cameras (often called "spy cameras" or subminiature cameras) has now greatly increased. Some consumer compact digital cameras are now so small that in previous decades they would have qualified as "spy cameras", and digital cameras of 5 megapixels or more are now being embedded in some mobile camera phones.
Some fine art photographers have displayed a fascination with the forms of secret voyeuristic photography. Voyeuristic photography has also been centrally explored in movies such as Powell & Pressburger's Peeping Tom, and Michelangelo Antonioni's Blowup, and has appeared to comic effect in films such as Gregory's Girl and American Pie.
There are various personal privacy laws in different countries which also impact on the secret photography of individuals, and on the publication of any resulting pictures. France for instance, has very strict laws against publication of such images,[3] while the British tabloid press will publish a variety of secret photography. Examples of the British situation include the publication of photos of Princess Diana secretly taken in a gym,[4] and the publication of secretly taken photos of Naomi Campbell which led to a major court case.[5]
News gathering organisations and media trade unions issue ethical guidelines to their members on the use of secret and telephoto lens photography.[6]
