Photoshop

Photoshop is a computer-assisted editing, processing and drawing software, launched in 1990 on MacOS and then in 1992 on Windows that revolutionized photography and up to the design that could be made.

Edited by Adobe, it is mainly used for the processing of digital photographs, but also serves for the ex nihilo creation of images.

It works mainly on raster images because the images consist of a grid of dots called pixels. The interest of these images is to reproduce subtle gradations of colors.
