Adobe Photoshop is a raster graphics editor developed and published by Adobe Inc. for macOS and Windows. Photoshop was created in 1988 by Thomas and John Knoll.
Since then, it has become the de facto industry standard in raster graphics editing, such that the word “photoshop” has become a verb as in “to Photoshop an image,” “photo shopping” and “Photoshop contest”, though Adobe discourages such use. It 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 has vast support for graphic file formats but also uses its own PSD and PSB file formats which support all the aforementioned features.
Older versions of Photoshop are no longer available for download from Adobe. However, there are a few ways to get your hands on an older version of the software.
One way is to purchase a copy of Photoshop from a third-party retailer. There are also a few websites that offer older versions of Photoshop for download, though it is important to note that these are not official Adobe websites.
If you’re looking for an older version of Photoshop, your best bet is to purchase a copy from a third-party retailer or look for it on one of the many unofficial Adobe websites.
