Apple has posted an update to Aperture, its professional photo cataloging and editing software. The new version is available for download from the Mac App Store.
Aperture provides pro-level cataloging and metadata management capabilities, along with nondestructive editing tools and easy workflow with external image editors like Photoshop.
New in the 3.5.1 release is a fix for Temperature and Tint White Balance. Face detection overlays now work correctly. An issue has been resolved involving metadata field entry when arrowing between photos. Stability improvements have also been made.
