Pros: cost effective, non destructive to original images, easy to learn, pairs well with a mac o/s 10 64 bit
Cons: best with lots of ram, it's addictive, too much fun
"I've been using this s/ w on my iMac with images from my Canon 7D and love it. The tools are easy to use and very effective at manipulating details which were missed at the time of image capture in RAW format. I wouldn't use any other tool and appreciate the user friendliness of this tool over aperture."
