Flying Meat has launched Acorn 2.0, an update to its image-editing software. The bitmap-based software uses layers and blending modes to implement photo-editing techniques, allowing for experimentation and easy placement of text and objects, while protecting the image at the base. It has screen shot capabilities, can export images for the web, and has filters with chaining support.

Version 2.0 adds 64-bit support, a new Acorn file format and RAW image import. It adds darkroom tools like burn, dodge and smudge brushes, and a clone tool. A perspective transform tool has been added while the transform and crop tools have been revamped. Rulers have been added and layers can now be grouped.

Acorn 2.0 requires Mac OS X 10.6 or higher. It costs $50 with bundle discounts and multi-license discounts available.
