The camera has a long and distinguished history as a means of recording phenomena from the first use by Daguerre and Fox-Talbot, such as astronomical events (eclipses for example), small creatures and plants when the camera was attached to the eyepiece of microscopes (in photomicroscopy) and for macro photography of larger specimens. The camera also proved useful in recording crime scenes and the scenes of accidents, such as the Wootton bridge collapse in 1861. The methods used in analysing photographs for use in legal cases are collectively known as forensic photography.
By 1853, Charles Brooke had invented a technology for the automatic registration of instruments by photography. These instruments included barometers, thermometers, psychrometers, and magnetometers, which recorded their readings by means of an automated photographic process.

Photography has become ubiquitous in recording events and data in science and engineering, and at crime scenes or accident scenes. The method has been much extended by using other wavelengths, such as infrared photography and ultraviolet photography, as well as spectroscopy. Those methods were first used in the Victorian era and developed much further since that time.

Social and cultural implications

There are many ongoing questions about different aspects of photography. In her writing "On Photography" (1977), Susan Sontag discusses concerns about the objectivity of photography. This is a highly debated subject within the photographic community.Sontag argues, "To photograph is to appropriate the thing photographed. It means putting one’s self into a certain relation to the world that feels like knowledge, and therefore like power."Photographers decide what to take a photo of, what elements to exclude and what angle to frame the photo, and these factors may reflect a particular socio-historical context. Along these lines it can be argued that photography is a subjective form of representation.
Modern photography has raised a number of concerns on its impact on society. In Alfred Hitchcock's Rear Window (1954), the camera is presented as promoting voyeurism. 'Although the camera is an observation station, the act of photographing is more than passive observing'.Michal Powell's Peeping Tom (1960) portrays the camera as both sexual and sadistically violent technology that literally kills in this picture and at the same time captures images of the pain and anguish evident on the faces of the female victims.[citation needed]
"The camera doesn't rape or even possess, though it may presume, intrude, trespass, distort, exploit, and, at the farthest reach of metaphor, assassinate - all activities that, unlike the sexual push and shove, can be conducted from a distance, and with some detachment."
Digital imaging has raised ethical concerns because of the ease of manipulating digital photographs in post-processing. Many photojournalists have declared they will not crop their pictures, or are forbidden from combining elements of multiple photos to make "photomontages", passing them as "real" photographs. Today's technology has made image editing relatively simple for even the novice photographer. However, recent changes of in-camera processing allows digital fingerprinting of photos to detect tampering for purposes of forensic photography.
Photography is one of the new media forms that changes perception and changes the structure of society.[38] Further unease has been caused around cameras in regards to desensitization. Fears that disturbing or explicit images are widely accessible to children and society at large have been raised. Particularly, photos of war and pornography are causing a stir. Sontag is concerned that "to photograph is to turn people into objects that can be symbolically possessed." Desensitization discussion goes hand in hand with debates about censored images. Sontag writes of her concern that the ability to censor pictures means the photographer has the ability to construct reality.
One of the practices through which photography constitutes society is tourism. Tourism and photography combine to create a "tourist gaze" in which local inhabitants are positioned and defined by the camera lens. However, it has also been argued that there exists a "reverse gaze" through which indigenous photographees can position the tourist photographer as a shallow consumer of images.
Additionally, photography has been the topic of many songs in popular culture.

Law

Main article: Photography and the law

Photography is both restricted as well as protected by the law in many jurisdictions. Protection of photographs is typically achieved through the granting of copyright or moral rights to the photographer. In the UK a recent law (Counter-Terrorism Act 2008) increases the power of the police to prevent people, even press photographers, from taking pictures in public places

Types of Photography

Photographic work can be divided into dozens of categories, many with lots of sub-categories. The following list describes some common types of photography.

Aerial                                                
From a plane, helicopter, balloon or other airborne device.
Adventure, Action                   
Adventure sports, daring feats, etc.
Amateur                                           
Any type of photography practiced by non-professionals.
Animal, Pet                                      
Pets and their relationships with humans. Note that the human content is often as important as the animal.
Architecture, Real Estate               
The art of making property appear attractive. Often involves panoramic photography.
Artistic                                              
Photography in which creative composition is the goal.
Astrophotography                          
Space photography, through a telescope.
Aura                                                   
A controversial type of photography which some claim can photograph a person's aura. Often confused with Kirlian photography.
Black & White                                 
Not simply photography without colour, black and white photography explores shapes, tones and textures. Shadows and highlights become much more important.
Camera Phone                               
 "Convenience" photography using a mobile phone's built-in camera. While not the best quality, camera phones have opened a new world of spontaneous, on-the-spot photo opportunities.
Commercial                                  
Product shots, advertising, etc.
Digiscoping                                      
Photography through a telescope or binoculars.
Documentary                                 
Journalism, Events, Historical, Political, etc.
Event                                                
Concerts, parties, festivals, weddings, etc.
Forensic                                          
Police and legal photography.
Infrared                                            
Photography in which the recording medium is sensitive to infrared light rather than the normal visible light spectrum.
Large Format                                   
For use on posters, billboards, etc.
Kirlian                                               
A type of contact print photography in which an object touching a photographic plate is connected to a high voltage source, creating an aura-like image. Often confused with aura photography.
Macro                                               
The art of photographing very small and/or close-up objects.
Medical                                             
Specialized photography for clinical purposes, i.e. to help reveal and diagnose illness.
Microscopic                                     
Any technique for photographing objects too small to be visible to humans.
Modeling

 Involves taking two photos simultaneously to simulate 3-D vision.
Stock                                                 
Photographs taken for distribution to other people, for use in their projects. These photos tend to be quite generic, e.g. people working, landscapes, places, etc.
Time-lapse                                       
Photographs with a very long exposure, used to illustrate something happening over time. A popular example is a street at night with car lights blurred into long lines.
Travel                                                
Photography to showcase locations, illustrate travel literature, etc.
