Paper Abstract

Investigation of optical spatial filtering as a method for restoring fogged photographic imagery indicates that acceptable restorations are possible if the exposure pattern features a low contrast or a low fogging level. At higher contrast or fogging levels, the restoration procedure suffers significant error. The error, which is due primarily to the nonlinear nature of the photographic process, appears as a failure to reproduce the lightly exposed regions of the photographic transparency.
