HAMBURG -- Dec. 12 -- The software for correction of optical deficiencies in professional photography, Acolens, is now available as a free download in a demo version.

Acolens, which was introduced in July and awarded with the "Star Award -- Highlight of Photokina 2006," can now be downloaded by photographers for free at the company's Web site http://www.nurizon-software.com. With this move the company finally gives in to a repeatedly-stated request in the photographic community.

Based on highly precise lens calibration methods Acolens corrects the optical image deficiencies distortions, vignetting and focus fall-off toward the edges. As a result, photographs are optimized based on objective criteria instead of mere manipulation.

The Acolens demo already provides features that will shortly be made available to existing users with the next free update of the software. Among those features is a semi-automatic assignement of lens profiles, the opportunity of adjusting the size proportions between the light table and the preview and the red gridlock is now rotatable for non-horizontal takings allowing easier assessment of the distortion correction in the preview.
