Adobe previously offered Photoshop as a standalone program in the Adobe Creative Suite, as signified in its full title “Photoshop CS”. When Adobe replaced its suite of standalone products with the web-based Creative Cloud software, Photoshop CS became Photoshop CC. You can still use older versions of the software, but you won't have access to newer features introduced with the Creative Cloud. Beyond the differences in name and release dates, Photoshop CC differs from older versions of Photoshop in that it requires a subscription to use. There are individual and group options, as well as discounted versions for educators and students. One of the upsides to Photoshop CC's subscription model is that Adobe updates it regularly, and it's accessible online. Cloud-based storage and the ability to access your files from any device are more perks.
