<p>A mask (1) is adapted for superimposing on a photo carrying a motif in form of e.g. a portrait (7) that is to be accentuated. The mask is made of a transparent plastics foil as by means of e.g. coloured raster is made opaque in a peripheral region (2) surrounding a transparent, central area (3) without raster. The peripheral region (2) and the central area (3) is separated by a relatively narrow, transitional zone (4) with increasing distance between the raster so as the transitional zone gradually fades out into the transparent, central area (3). The mask may be employed in the same simple manner as a passe-partout frame for accentuating one particular motif on a photo, and with the same good visual effect achieved by a traditionally phototechnical method for integrally to provide a photo with a neutral peripheral region gradually fading out via a soft transitional zone into the desired motif.</p> |
