There is a great write-up on Mark Hamburg leaving Adobe and pursuing opportunities at Microsoft.
“Mark Hamburg, founder of Adobe Photoshop Lightroom and former architect of Photoshop is leaving Adobe for a post at Microsoft. Mark, who was the second engineer hired to work on Photoshop after Thomas Knoll, has been at Adobe for over 17 years. He joined Adobe in the fall of 1990–the year Photoshop 1.0 shipped.“
What is interesting is that Mark will apparently be leading a team that will be working on the future of OS User Experience at Microsoft.
“Mark was invited by David Vaskevitch to come lead a team working on the future of OS User Experience at Microsoft. This is the way Mark phrased it: Now, given that I find the current Windows experience really annoying and yet I keep having to deal with it, this opportunity was a little too interesting to turn down. I can’t imagine doing serious imaging anywhere other than Adobe, but, I needed to do something other than imaging for a while.“
