Digital GEM is a technology developed by Applied Science Fiction that reduces film grain from a scanned image. GEM stands for Grain Equalization & Management. It is able to analyze film's grain pattern and then reduce or remove film graininess without harming the colors, sharpness, and detail content of the image. This technology is based on a complex set of algorithms and works after the scanning process.
