Photography is the art, application, and practice of creating images by recording light, 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, and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.
Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, modern astrophotography has the ability to image objects outside of the visible spectrum of the human eye such as dim stars, nebulae, and galaxies. This is accomplished through long time exposure as both film and digital cameras can accumulate and sum photons over long periods of time or using specialized optical filters which limit the photons to a certain wavelength.
A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as telephoto lenses, although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group.
Pictorialism is an international style and aesthetic movement that dominated photography during the later 19th and early 20th centuries. There is no standard definition of the term, but in general it refers to a style in which the photographer has somehow manipulated what would otherwise be a straightforward photograph as a means of creating an image rather than simply recording it. Typically, a pictorial photograph appears to lack a sharp focus, is printed in one or more colors other than black-and-white and may have visible brush strokes or other manipulation of the surface. For the pictorialist, a photograph, like a painting, drawing or engraving, was a way of projecting an emotional intent into the viewer's realm of imagination.
Underwater photography is the process of taking photographs while under water. It is usually done while scuba diving, but can be done while diving on surface supply, snorkeling, swimming, from a submersible or remotely operated underwater vehicle, or from automated cameras lowered from the surface.
Photojournalism is journalism that uses images to tell a news story. It usually only refers to still images, but can also refer to video used in broadcast journalism. Photojournalism is distinguished from other close branches of photography by having a rigid ethical framework which demands an honest and impartial approach that tells a story in strictly journalistic terms. Photojournalists contribute to the news media, and help communities connect with one other. They must be well-informed and knowledgeable, and are able to deliver news in a creative manner that is both informative and entertaining.
Color photography is a type of photography that uses media capable of capturing and reproducing colors. By contrast, black-and-white or gray-monochrome photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.
Roger Fenton was a British photographer, noted as one of the first war photographers.
Fine-art photography is photography created in line with the vision of the photographer as artist, using photography as a medium for creative expression. The goal of fine-art photography is to express an idea, a message, or an emotion. This stands in contrast to representational photography, such as photojournalism, which provides a documentary visual account of specific subjects and events, literally representing objective reality rather than the subjective intent of the photographer; and commercial photography, the primary focus of which is to advertise products or services.
Wedding photography is a specialty in photography that is primarily focused on the photography of events and activities relating to weddings. It may include other types of portrait photography of the couple before the official wedding day, such as a pre-wedding engagement session, in which the photographs are later used for the couple's wedding invitations. On the wedding day, the photographer(s) will provide portrait photography as well as documentary photography to document the different wedding events and rituals throughout the day(s).

Clarence Hudson White was an American photographer, teacher and a founding member of the Photo-Secession movement. He grew up in small towns in Ohio, where his primary influences were his family and the social life of rural America. After visiting the World's Columbian Exposition in Chicago in 1893, he took up photography. Although he was completely self-taught in the medium, within a few years he was internationally known for his pictorial photographs that captured the spirit and sentimentality of America in the early twentieth century. As he became well known for his images, White was sought out by other photographers who often traveled to Ohio to learn from him. He became friends with Alfred Stieglitz and helped advance the cause of photography as a true art form. In 1906 White and his family moved to New York City in order to be closer to Stieglitz and his circle and to further promote his own work. While there he became interested in teaching photography and in 1914 he established the Clarence H. White School of Photography, the first educational institution in America to teach photography as art. Due to the demands of his teaching duties, his own photography declined and White produced little new work during the last decade of his life. In 1925 he suffered a heart attack and died while teaching students in Mexico City.
Analog photography, also known as film photography, is a term usually applied to photography that uses chemical processes to capture an image, typically on paper, film or a hard plate. These processes were the only methods available to photographers for more than a century prior to the invention of digital photography, which uses electronic sensors to record images to digital media. Analog electronic photography was sometimes used in the late 20th century but soon died out.
The Photo-Secession was an early 20th century movement that promoted photography as a fine art in general and photographic pictorialism in particular.
