Earlier this week Apple Computer released the latest iteration of its post-production photography software, Aperture 1.5 to retail consumers, but on Friday, the firm announced that the tool will be available for download as well.

The new software, delivering new libraries for photographers and integration with other Apple software, is now available on Apple's website for free upgrades for users who purchased previous versions.

Aperture has given photographers around the globe the confidence to work in exciting new ways, said Rob Schoeben, Apple's vice president of Applications Product Marketing. Now with Aperture 1.5, we've opened the library and extended the workflow to provide a solution that is as flexible as it is powerful.

Aperture 1.5 is available to order for new customers for a suggested retail price of $299.
