George has a camera that shoots in RAW, and wants to know what software for Mac will handle this best. Leo says that RAW is the uncompressed, raw data coming from the sensor, so it's huge, unwieldy, and unprocessed. The Mac already has a program that can handle those RAW files, though. iPhoto should handle it, but Apple Aperture is another good option that will give him additional capabilities. Leo also likes Adobe Lightroom.
