I must admit, CCD Fix may have very limited applicability. It was designed for use with my Olympus D-600L camera. Most D-600L cameras produce images that can exhibit light colored pixels at long shutter speeds. These light pixels are CCD pixels that react differently, or have higher "dark current." CCD Fix basically allows you to take a dark exposure with your camera and set this dark exposure as a mask to be subtracted from other images. The utility also does a check of the CCD and informs the user of the number of pixels that were in need of correction, and the value of the worst (lightest) pixel. CCD Fix will then allow you to select any number of files in the same directory to be "fixed" by subtracting the dark frame. The result is more consistent images in low light. CCD Fix currently only works with the D-600L camera, and possibly the D-500L (not tested yet). The main reason for the specificity is that CCD Fix looks for the "SHUTTER=" value in the JPG file so that it can correctly compensate for different shutter speeds. I am not aware of any other cameras that embed this information in the JPG file at this time.
