Photoshots of skin and hair - "high - key"

High-key lighting is a style of lighting for film, television, or photography that aims to reduce the lighting ratio present in the scene. This was originally done partly for technological reasons, since early film and television did not deal well with high contrast ratios, but now is used to suggest an upbeat mood. It is often used in sitcoms and comedies. High-key lighting is usually quite homogeneous and free from dark shadows.

Nude photography is a style of art photography which wants to show the naked body as a form of art. This is different form erotic photography, which has an erotic component. For many photographers, nude photography is a study of the human body, much like some paintings did. Photographing a person to be recognised is called portrait. Nude photography focuses on showing the human body, often the face is not visible.

Skin and hair - photo impressions - black and white photography and color


The first color plate, Autochrome, invented by the French Lumiere Brothers reached the market in 1907. It was based on a 'screen-plate' filter made of dyed dots of potato starch, and was the only color film on the market until German Agfa introduced the similar Agfacolor in 1932. In 1935, American Kodak introduced the first modern ('integrated tri-pack') color film which was developed by Polish constructor Jan Szczepanik. It was Kodachrome based on three colored emulsions. This was followed in 1936 by Agfa's Agfacolor Neue. Unlike the Kodachrome tri-pack process, the color couplers in Agfacolor Neue were integral with the emulsion layers, which greatly simplified the film processing. Most modern color films, except Kodachrome, are based on the Agfacolor Neue technology. Instant color film was introduced by Polaroid in 1963.

Practical application of the technique was held back by the very limited color response of early film; however, in the early 1900s, following the work of photo-chemists such as H. W. Vogel emulsions with adequate sensitivity to green and red light at last became available.

One of the early methods of taking color photos was to use three cameras. Each camera would have a color filter in front of the lens. This technique provides the photographer with the three basic channels required to recreate a color image in a darkroom or processing plant. Russian photographer Sergei Mikhailovich Prokudin Gorskii developed another technique, with three color plates taken in quick succession.
