Apple released Aperture 1.5.3 on Thursday. The update to the professional image management and touch up application fixed problems with entering and exiting full screen mode and generating thumbnails for adjusted images. It also addressed problems with image previews in external editors, importing Leaf Aptus 22 and Aptus 75 images, preserving imported folder hierarchy, working with ColorSync settings, and more.
The Aperture 1.5.3 update is free for licensed users, and is available through Software Update or as a downloadable installer at the Apple Web site.
