This is a list of serious injuries and deaths in which one or more subjects of a selfie were killed or injured, either before, during or after having taken a photo of themselves, with the accident at least in part attributed to the taking of the photo.
The United States Department of Transportation estimated that during 2014, the so-called "year of the selfie", 33,000 people were injured while driving and using a cell-phone in some fashion, which can include talking, listening, and "manual button/control actuation" including taking, uploading, downloading, editing, or opening of selfies. A 2015 survey by Erie Insurance Group found that 4% of all drivers admitted to taking selfies while driving.
The Washington Post reported in January 2016 that "about half" of at least 27 "selfie related" deaths in 2015 had occurred in India. No official datasets on the number of people who died taking selfies in India exists, but reports show from 2014 up to August 2016, there have been at least 54 deaths in India while taking selfies. The Indian Ministry of Tourism asked states to identify and barricade 'selfie danger' areas, its first national attempt to deal with the selfie deaths. Mumbai Police identified at least 16 danger zones after a man drowned attempting to save a selfie-taker. No-selfie zones were also established in certain areas of the Kumbh Mela because organizers feared bottlenecks caused by selfie-takers could spark stampedes.
A 2018 study of news reports showed that between October 2011 and November 2017, there were 259 selfie deaths in 137 incidents reported globally, with the highest occurrences in India, followed by Russia, United States, and Pakistan. The mean age was 23 years old, with male deaths outnumbering female about three to one.
Pigeon photography is an aerial photography technique invented in 1907 by the German apothecary Julius Neubronner, who also used pigeons to deliver medications. A homing pigeon was fitted with an aluminium breast harness to which a lightweight time-delayed miniature camera could be attached. Neubronner's German patent application was initially rejected, but was granted in December 1908 after he produced authenticated photographs taken by his pigeons. He publicized the technique at the 1909 Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the 1910 and 1911 Paris Air Shows.
Initially, the military potential of pigeon photography for aerial reconnaissance appeared interesting. Battlefield tests in World War I provided encouraging results, but the ancillary technology of mobile dovecotes for messenger pigeons had the greatest impact. Owing to the rapid perfection of aviation during the war, military interest in pigeon photography faded and Neubronner abandoned his experiments. The idea was briefly resurrected in the 1930s by a Swiss clockmaker, and reportedly also by the German and French militaries. Although war pigeons were deployed extensively during World War II, it is unclear to what extent, if any, birds were involved in aerial reconnaissance. The United States Central Intelligence Agency (CIA) later developed a battery-powered camera designed for espionage pigeon photography; details of its use remain classified.
The construction of sufficiently small and light cameras with a timer mechanism, and the training and handling of the birds to carry the necessary loads, presented major challenges, as did the limited control over the pigeons' position, orientation and speed when the photographs were being taken. In 2004, the British Broadcasting Corporation (BBC) used miniature television cameras attached to falcons and goshawks to obtain live footage, and today some researchers, enthusiasts and artists similarly deploy crittercams with various species of animals.

The rapatronic camera (a portmanteau of rapid action electronic) is a high-speed camera capable of recording a still image with an exposure time as brief as 10 nanoseconds.
The camera was developed by Harold Edgerton in the 1940s and was first used to photograph the rapidly changing matter in nuclear explosions within milliseconds of detonation, using exposures of several microseconds. To overcome the speed limitation of a conventional camera's mechanical shutter, the rapatronic camera uses two polarizing filters and a Faraday cell (or in some variants a Kerr cell). The two filters are mounted with their polarization angles at 90° to each other, to block all incoming light. The Faraday cell sits between the filters and changes the polarization plane of light passing through it depending on the level of magnetic field applied, acting as a shutter when it is energized at the right time for a very short amount of time, allowing the film to be properly exposed.
In magneto-optical shutters, the active material of the Faraday cell (e.g. dense flint glass, which reacts well to a strong magnetic field) is located inside an electromagnet coil, formed by a few loops of thick wire. The coil is powered from a pulse forming network by discharging a high-voltage capacitor (e.g. 2 microfarads at 1000 volts), into the coil via a trigatron or a thyratron switch. In electro-optical shutters, the active material is a liquid, typically nitrobenzene, located in a cell between two electrodes. A brief impulse of high voltage is applied to rotate the polarization of the passing light.
For a film-like sequence of high-speed photographs, as used in the photography of nuclear and thermonuclear tests, arrays of up to 12 cameras were deployed, with each camera carefully timed to record sequentially. Each camera was capable of recording only one exposure on a single sheet of film. Therefore, in order to create time-lapse sequences, banks of four to ten cameras were set up to take photos in rapid succession. The average exposure time used was three microseconds.

Vivian Dorothy Maier (February 1, 1926 – April 21, 2009) was an American street photographer whose work was not discovered and recognized until after her death. She worked for about forty years as a nanny, mostly in Chicago's North Shore, while she pursued her photography. She took more than 150,000 photographs during her lifetime, primarily of the people and architecture of Chicago, New York City, and Los Angeles, although she also traveled and photographed worldwide.
During her lifetime, Maier's photographs were unknown and unpublished; many of her negatives were never printed. A Chicago collector, John Maloof, acquired some of Maier's photos in 2007, while two other Chicago-based collectors, Ron Slattery and Randy Prow, also found some of Maier's prints and negatives in her boxes and suitcases around the same time. Maier's photographs were first published on the Internet in July 2008, by Slattery, but the work received little response. In October 2009, Maloof linked his blog to a selection of Maier's photographs on the image-sharing website Flickr, and the results went viral, with thousands of people expressing interest. Maier's work subsequently attracted critical acclaim, and since then, Maier's photographs have been exhibited around the world.
Her life and work have been the subject of books and documentary films, including the film Finding Vivian Maier (2013), which premiered at the Toronto International Film Festival, and was nominated for the Academy Award for Best Documentary Feature at the 87th Academy Awards.
