As Adobe inches towards the debut of Lightroom 3.0, it has rolled out the software's release candidate, version 2.7, adding raw camera support for nine new cameras. The newly supported cameras include the Canon EOS 550D (Digital Rebel T2i/ EOS Kiss X4 Digital), Kodak Z981, Leaf Aptus-II 8, Leaf Aptus-II 10R, Mamiya DM40, Olympus E-PL1, Panasonic G2, Panasonic G10, and the Sony A450. The update also raises the cache limit to 200 GB and fixes a slideshow playback crashing bug for Windows users. Coinciding with this update are the releases of the Photoshop Camera Raw 5.7 and DNG Converter 5.7 Release Candidates. ($299 new, free updates for existing Lightroom and Photoshop users, 75.8/51.8/47.7 MB)
Disable Caps Lock
If you find yourself pressing the Caps Lock key accidentally as much as I do, note that you can disable it entirely in Mac OS X. Open the Keyboard & Mouse preference pane, click the Modifier Keys button, and in the dialog that appears, select No Action from the Caps Lock pop-up menu. You could remap it to another modifier instead, but that might make using differently configured Macs more difficult.
