Photoshop is a popular image changing software package. It is widely used by photographers for photo editing (fixing colors, reducing noise, adding effects, fixing brightness/contrast) and by graphic designers and Web designers to create and change images for web pages.Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models. With the February 2020 update (version 21.1) Photoshop now can iteratively fill multiple areas of an image without having to leave content-aware fill workspace. This version improved GPU based lens blur quality and provided performance improvements, such as accelerating workflows with smoother panning, zooming and navigation of documents.
