When Apple released Aperture update 3.5.1 late Thursday afternoon—an update to its pro photo management software—the fix was designed to solve face detection problems. The update is free for version 3 users.
In addition to face detection, the new version also corrects problems with temperature and tint white balance and fixed a problem with adding metadata when moving between photos via the arrow key. The update also promises to improve overall stability.
Aperture is available from the App Store for £60.
