Nurizon, a German hard- and software developer is proud of the launch of its professional "Acolens" software tool for photographers. Optical deficiencies on photographs, i.e. distortions, vignetting, and focus falloff toward the edges have increased with the emergence of digital photography. With "Acolens" these deficiencies can now be corrected in a professional manner. Based on the calibration of popular lens models so called lens profiles are stored in a preinstalled lens databank. Photographers who prefer to calibrate their individual lenses themselves can do so with the also available "Acolens" Reference Chart. "Finally, there is a professional tool for correction of lens deficiencies that treats images neutrally rather than just manipulating them", says Fria Hagen, a professional photographer and tester of the software’s beta version. "Acolens" is available at the company’s website.
