Mary Jo Foley speculates about Lightroom designer Mark Hamburg's departure to Microsoft:

What?s Microsoft want with Adobe Photoshop guru Mark Hamburg, who recently joined the Redmond juggernaut?

Hamburg a programmer who has been part of the Adobe Photoshop team since version 2.0 and helped lead the Photoshop Lightroom one, is now a Softie, as Stephen Shankland reported on April 28.

The official word from Microsoft is Hamburg will be working on unnamed ?user experience? efforts. My bet is Hamburg will be instrumental in helping Microsoft bring to market its Photoshop Lightroom competitor, which is codenamed ?SmartFlow.?
