Photoshop is a computer-assisted retouching, processing and drawing
software, launched in 1990 on MacOS then in 1992 on Windows.Published by Adobe, it is mainly used for processing digital photographs,
but is also used for creating ex nihilo images.He works mainly on raster images because the images consist of a grid of
points called pixels. The interest of these images is to reproduce subtle
gradations of colors.In 1987, Thomas Knoll, a student at the
University of Michigan, began writing a program to display grayscale images on
a monochrome screen. Called "Display", this program attracted the
attention of his brother John Knoll, then employed at Industrial Light &
Magic. The latter recommends that he make it a full-fledged image editor.
Thomas Knoll then takes six months off to work with his brother on the program,
which becomes "ImagePro". Later in the year, T. Knoll renamed the
program “Photoshop” (literally “photo workshop”). Then he collaborated with the
scanner manufacturer Barneyscan to distribute copies with a film scanner, a
rare and expensive device at the time. A total of about 200 copies are sold
this way.
