Apple has today (Wednesday, 19 October 2005 17:55 GMT) announced Aperture, a new digital photography workflow, organization and manipulation application aimed specifically at professional photographers. Aperture includes advanced RAW workflow, a unique user interface and an interesting feature called Stacks which groups images together based on the time differential between shots.
First question to pop up in anyone’s mind would obviously be: is this intended to replace Adobe Photoshop? Well, it does have non-destructive basic editing, but according to this article, Adobe believes Apple Aperture is not a competitor to Photoshop at all, and will serve as a worthy complementary application, apparently targetted mainly to professional photographers.
