Now you can enjoy a free 30-day trial of Aperture 1.5, the powerful all-in-one post-production tool for serious photographers. Apple invites users to try it to see how easy it is to import, manage, edit, catalog, organize, adjust, publish, export, and archive your RAW, JPEG, TIFF, and PSD images.
You can download the Aperture Trial in English, French, German, or Japanese, but you first need to read and agree to the participation terms before requesting a Trial Serial Number and downloading the software.
Once you fill out the form (link below) and agree to the terms, Apple will send you the serial number you’ll use to activate Aperture for the length of the trial.
Note: If you download the free Aperture Trial, please note that the software cannot be updated to Aperture 1.5.1. The Aperture 1.5.1 Update will update ONLY fully licensed copies of Aperture.
