burning-in

Definition: (1) Digital image manipulation technique that mimics darkroom burning-in: applied by brush of varying sizes and has effect of darkening i.e. increasing grey content (i.e. equal amounts of R, G and B) of affected pixels. (2) Darkroom technique for altering local contrast and density during printing by giving local exposure to a specific area with rest of print masked off to prevent unwanted exposure elsewhere. * With negative-positive working processes, burning-in increases density - makes darker - at the burnt-in area; with positive-positive working e.g. R-type prints, burning-in decreases density locally i.e. makes the area lighter.
