Open Source Camera Hacking
Some folks at Stanford are working on a project they call Computational Photography. Cool to see digital photography becoming more hackable in the capture phase. The Linux based "Frankencamera" looks nice!
I also recently discovered digiKam, a KDE based professional photo management tool. I have not really played with it but it looks pretty powerful tool that combines some of the features of both GIMP and F-Spot, along the lines of Aperture.
