Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.[1]
Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

The history of photography began in remote antiquity with the discovery of two critical principles: camera obscura image projection and the observation that some substances are visibly altered by exposure to light. There are no artifacts or descriptions that indicate any attempt to capture images with light sensitive materials prior to the 18th century. Around 1717 Johann Heinrich Schulze captured cut-out letters on a bottle of a light-sensitive slurry, but he apparently never thought of making
A selfie (/ˈsɛlfi/)[1] is a self-portrait digital photograph, typically taken with a digital camera or smartphone, which may be held in the hand or supported by a selfie stick. Selfies are often shared on social media, via social networking services such as Facebook, Twitter, Snapchat, and Instagram.
They are often casual in nature (or made to appear casual). "Selfie" typically refers to self-portrait photos taken with the camera held at arm's length, as opposed to those taken by using a
A snapshot is a photograph that is "shot" spontaneously and quickly, most often without artistic or journalistic intent and usually made with a relatively cheap and compact camera.
Common snapshot subjects include the events of everyday life, often portraying family members, friends, pets, children playing, birthday parties and other celebrations, sunsets, tourist attractions and the like.
Snapshots can be technically "imperfect" or amateurish: poorly framed or composed, out of focus, and/or
Conceptual / experimental photography is a type of photography that illustrates an idea. There has been illustrative photographs made since the medium's invention, for example in the earliest staged photographs, such as Hippolyte Bayard's Self Portrait as a Drowned Man (1840). However, the term Conceptual Photography derives from Conceptual Art a movement of the late 1960s. Today the term is used to describe either a methodology or a genre.

Wildlife photography is a genre of photography concerned with documenting various forms of wildlife in their natural habitat.
As well as requiring photography skills, wildlife photographers may need field craft skills. For example, some animals are difficult to approach and thus a knowledge of the animal's behavior is needed in order to be able to predict its actions. Photographing some species may require stalking skills or the use of a hide/blind for concealment.

Portrait photography or portraiture in photography is a photograph of a person or group of people that captures the personality of the subject by using effective lighting, backdrops, and poses. A portrait picture might be artistic, or it might be clinical, as part of a medical study. Frequently, portraits are commissioned for special occasions, such as weddings or school events. Portraits can serve many purposes, from usage on a personal Web site to display in the lobby of a
Landscape photography shows spaces within the world, sometimes vast and unending, but other times microscopic. Landscape photographs typically capture the presence of nature but can also focus on man-made features or disturbances of landscapes. Landscape photography is done for a variety of reasons. Perhaps the most common is to recall a personal observation or experience while in the outdoors, especially when traveling. Others pursue it particularly as an outdoor lifestyle, to be involved with
