Aperture 2

I'm thrilled with the new enhancements in Aperture 2. Among my favorites is the Advanced pane of the enhanced "Highlights & Shadows" controls. It really helped me bring out the definition in this photo.

There are many other great features, and this isn't the only one that I used on this photo, but it made the biggest difference.

Here's the final photo:

Note: Aperture 2 doesn't display a side-by side comparison like this, nor does it overlay the controls in this way. This is a composite illustration that I created using The Gimp.
