Adobe Photoshop is a raster graphics editor created and distributed by Adobe Systems for Windows and OS X. Photoshop was made in 1988 by Thomas and John Knoll. From that point forward, it has turned into the true business standard in raster illustrations altering, such that the expressions “photoshopping” and “photoshop challenge” were conceived. It can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models including RGB, CMYK, Lab color space, spot color and duotone. Photoshop has vast support for graphic file formats but also uses its own
PSB file formats which support all the aforementioned features. In addition to raster graphics, it has limited abilities to edit or render text, vector graphics, 3D graphics and video. Photoshop’s featureset can be expanded by Photoshop plug-ins, programs developed and distributed independently of Photoshop that can run inside it and offer new or enhanced features. Photoshop’s naming scheme was initially based on version numbers. However, on October 2004, following the introduction of Creative Suite branding, each new version of Photoshop was designated with “CS” plus a number; e.g. the eighth major version of Photoshop was Photoshop CS and the ninth major version was Photoshop CS2. Photoshop CS3 through CS6 were also distributed in two different editions: Standard and Extended. In June 2013, with the introduction of Creative Cloud branding, Photoshop’s licensing scheme was changed to that of software as a service and the “CS” suffixes were replaced with “CC”. Historically, Photoshop was bundled with additional software such as Adobe ImageReady, Adobe Fireworks, Adobe Bridge, Adobe Device Central and Adobe Camera RAW. Alongside Photoshop, Adobe also develops and publishes Photoshop Elements, Photoshop Lightroom, Photoshop Expressand Photoshop Touch. Collectively, they are branded as “The Adobe Photoshop Family”.
