Here's another cool utility that's been released recently, aimed at digital photography buffs (like me). It's an add-in for Windows that allows you to easily modify the "metadata" for digital photographs from directly within Windows Explorer. I love it because it works with my camera's RAW format. And it works with Windows XP (with Service Pack 2 or later) and Windows Vista!
