There’s a nifty — and free — new photo-management suite from the inventive folks at Google. Picasa 2.0 scans your system and arranges all your digitals in chronological order. But the editing goodies are the real story. Straighten photos, adjust highlights, banish red-eye, and add or reduce shadows. Then get creative with effects like sepia, soft-focus, black-and-white, and more. You’ll be adjusting color temperature in no time — even if you didn’t know color had temperature.
