A memory efficient system of storing color correction information for liquid crystal tuning filters when used with electronic imaging cameras to produce color images, which color correction information is stored with maximum possible gain to optimize accuracy preparatory to compression. The system bins the color correction image, for example, from a 4K.times.4K CCD sensor into a 500.times.500 or 1K.times.1K file, and then applies the JPEG and/or wavelet compression algorithm with a default configuration and/or a custom quantization table that emphasizes low frequency changes with more bits than high frequency changes with less bits. At the end of the compression, the compressed R, G, B files and an n-point correction executable algorithm are stored on floppy disk or CD ROM and are used to automatically take control of image enhancement when invoked by the photographer.
