Masterpiece Helper is an artistic error-correction plug-in. It works with Photoshop 7 and above on Mac OS X and Windows.

The De-Escher module repairs a number of easy-to-make drafting errors, such as problems with perspective or logical consistency. Masterpiece Helper automatically corrects for lighting, according to location, date and time, and for visual blurring. Additional features include Cubist Facet Smoother, De-Dadaizer and Pointillist Filter.
