 Advanced Processing Capabilities of FCR 4. Dynamic Range Control Processing (DRC) When computer processing is used to control the dynamic range of an image, the optical density can be set as appropriate for displaying regions of the subject that have been over or under exposed and might exist in blacked- or whited-out form. The image on the left, below, is an original CR image. First, the computer generates a filter (mask) image, shown in the middle. Then, the filter image is superimposed on the original. Results are shown in the image on the right, where optimal optical density was obtained without losing contrast in the original fields.
