1. A method of enhancing a digital image comprising: providing a digital image; decomposing the provided digital image into a multi-frequency band representation including a low frequency band image and multiple different high frequency band images; multiplying each of said high-frequency band images with a gain factor; summing together said unmodified low frequency band image and said modified high-frequency band images to produce a reconstructed digital image; and mapping said reconstructed digital image through a tone-scale look-up-table to map said reconstructed digital image to optical densities.
