Adobe Photoshop is a raster graph­ics ed­i­tor de­vel­oped and pub­lished by Adobe Inc. for Windows and ma­cOS. It was 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 a whole. Text from Wikipedia
