Adobe Photoshop may be a raster graphics editor developed and published by Adobe Inc. for Windows and macOS. it had been originally created in 1988 by Thomas and John Knoll. Since then, the software has become the industry standard not only in raster graphics editing, but in digital art as an entire . The software’s name has thus become a generic trademark, resulting in its usage as a verb photoshopping image although Adobe discourages such use. Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing and a number of other colour models including RGB, CMYK, HEX, spot colour, and duotone.
Photoshop uses its own PSD and PSB file formats to support these features. additionally to raster graphics, Photoshop has limited abilities to edit or render text and vector graphics (especially through clipping path for the latter), also as 3D graphics and video. Its feature set is often expanded by plug-ins; programs developed and distributed independently of Photoshop that run inside it and offer new or enhanced features.
