While geared primarily toward professional photographers it's great for amateurs or advanced amateurs too. It's not a replacement for Photoshop and will work with Photoshop as part of your workflow

There are over 100 new features from Aperture 1.5.

By the way, the Mac OSⁱ X Leopard 10.5.2 update also included support for more Camera RAW formats, including my Nikon D300! Yeah
