In December 2002, Hamburg invited Photoshop co-creator Thomas Knoll to brainstorm as part of a team at Schewe's studio, briefly calling the project 'SchewePaint'. In October 2002, he sent a prototype called 'PixelToy' to former colleague Jeff Schewe for evaluation. He resumed work on a project which he started in 1999 with a different approach to image editing, and developed a database that could store parameters for non-destructive image editing. However, Hamburg left the team after Photoshop 7 shipped in April 2002. Mark Hamburg was a senior engineer on the Adobe Photoshop team who eventually became the software architect.
