ABSTRACT:
A portable vignetting system attaches directly to the lens element of a photographic instrument enabling on-site creation of selected vignette effects with results comparable to those achieved under studio conditions. A main housing accommodates a camera lens at one end and a series of vignetting lids at the other. Each lid has formed therethrough an aperture of selected size and shape producing the desired vignette. Structure on the lid an housing cooperates to enable the lid to rotate with respect to the housing and to positively engage the housing at a multiplicity of precisely defined sites. The system may be used to create multiple vignette effects by combining different lids while making multiple exposures on a single film segment.
