1. A method for modifying an image comprising: (a) receiving an image having a first bit depth; (b) modifying said image to create a modified image resulting in a second bit depth different than said first bit depth in such a manner that the higher frequency content with respect to the lower frequency content of said image is attenuated, and attenuating the lower amplitude content of said higher frequency content with respect to the higher amplitude content of said higher frequency content; (c) modifying said modified image based upon said modified image and said lower frequency content of said image.
