If you don't know what RAW format is, you can stop reading now. If, on the other hand, you've just bought a brand new camera, shot a few pictures, and then bashed your head against your shiny white miracle machine because it doesn't recognize the file format -- well, I have good news! Apple's Digital Camera RAW Compatibility Update 3.3
adds RAW support for a bunch of brand new cameras to Aperture 3 and iPhoto '09.
Because there's nothing else to report, here's a list of the cameras that are now supported: Canon PowerShot SX1 IS, Olympus E-PL1, Panasonic Lumix DMC-G2, Panasonic Lumix DMC-G10, Samsung NX10, Sony Alpha DSLR-A390, Sony Alpha NEX-3, Sony Alpha NEX-5.
