Apple offers two free online Aperture seminars

Apple has announced two free online QuickTime seminars covering Aperture, their app for professional photographers. "Aperture: Streamline Your Workflow After the Shoot" is an introduction to the app from Product Marketing Manager Joe Schorr and Technical Marketing Manager Joseph Linaschke of Apple, while "Aperture Advanced" offers "an in-depth look at the first all-in-one post-production tool for photographers".

Apple's registration page for these seminars states that they're only available for a limited time, but doesn't mention how limited that time may be. You might have to act now if you don't want to regret later.
