Over at the (very slow) Adobe website there are lots of updates for Photoshop and Adobe Camera Raw. To help speed you up I have listed the direct links here:
Camera raw version 3.5 for windows
Photoshop version CS2 9.0.2 update for windows
Camera raw version 3.5 for OSX
Photoshop version CS2 9.0.2 update for OSX
Meanwhile back at the ranch, Phase one; the cheeky little monkeys, have been burning the midnight oil to release 3.7.5 of their C1 software, this supports new cameras (including the Leica M8) and has some other general improvements. You can get it here
Worth keeping up with these updates, download, install and forget.
