Adobe Photoshop is a raster graphics editor developed and published by Adobe Inc. It was originally created in 1988 by Thomas and John Knoll.
Since then, it has become the de facto industry standard in raster graphics editing, to the point that it has also become an informal verb meaning to edit images with Photoshop. Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing, and several color models including RGB, CMYK, CIELAB, spot color, and duotone. Photoshop uses its own PSD and PSB file formats to support these features.
The software’s name has thus become a generic trademark, leading to its usage as a verb (e.g., “to Photoshop an image”, “photoshopping” or “Photoshop job”) although Adobe discourages such use. Several features have been removed in recent releases of Photoshop, including support for image formats used in computer vision applications such as DPX.
Be aware that there are many different versions of Photoshop available, and each one has its own set of features and tools. Make sure you know which version you are using before beginning any project, as some features may not be available in older versions.
What are the different versions of Photoshop?
Adobe Photoshop is available in two different versions: the standard version and the extended version. The extended version includes all of the features of the standard version, plus additional features for working with three-dimensional images and video.
