Ars Technica has published a review of Apple's Aperture 1.1. The reviewer, Dave Girard, was very critical of version 1.0 of Aperture but says v1.1 is dramatically improved, especially its RAW file conversion quality.

The review contains comparative conversion examples from several Nikon, Canon, and Olympus cameras using Aperture 1.0, Aperture 1.1, Phase One Capture One Pro 3.7.4, and Adobe Lightroom beta 2.
