iPhone users now have additional reasons to be merry. Apple today announced the release of Aperture for iPhone, a new software that lets users post their image portfolios on .Mac Web galleries, or to the iPhone, iPod touch and Apple TV.

Users can switch between the Viewer and Browser modes using a single key command; an all-in-one heads up display lets users toggle between library, metadata and adjustment controls using a single tabbed inspector.

Aperture 2 adds more than 100 new features, a streamlined user interface and a new image processing engine, according to Apple. New imaging tools have been added, to help photographers recover highlights, bring out color vibrancy, manage local contrast definition, do soft-edged retouching and vignetting, and fine-tune RAW images.
