*** At Photoshop World West in September of 2013, Adobe announced the Photoshop Photography Program (PPP), a special introductory offer based on customer requests for a Creative Cloud package designed specifically for photographers. This was meant to be temporary and was initially available only as an upgrade for those who owned previous versions of Photoshop or Creative Suite. Due to the popularity of the program, we expanded it so that anyone could sign up, even first-time Adobe customers.

However, while the program remained popular, we wanted to create a permanent offer. With the Creative Cloud 2014 release, we announced the Creative Cloud Photography Plan (CCPP), which replaces the Photoshop Photography Program.

While the price remained the same, the early adopters are beneficiaries of additional perks. The Photoshop Photography Plan was a specialized version of a Creative Cloud Single App subscription. The Creative Cloud Photography Plan is an expansion of a Creative Cloud Free account. Those who signed up for the Photoshop Photography Program will continue to have access to everything they signed up for.
