Apple has announced Aperture v3.3, which features a series of updates including sharing its catalogue with the simpler iPhoto program that comes with iOS. Other improvements include support for AVCHD video, a revised Highlight & Shadows tool and more sophisticated white balance options. The software has also been designed to make use of the MacBook Pro's 'Retina' display. Aperture v3.3 is free to existing v3 users or can be bought for $79.99 from the Mac App Store.
