The Cavision 9-Stop Density Adjustable Viewing Filter is a neutral density viewing filter allowing you to previsualize lighting conditions for movie and photography use. The viewing filter has a 9-stop variable density range, from 0.3 to 2.7, which allows you to use this filter in situations from very dim to exceptionally bright. By using this filter to previsualize your shooting scene, you can compress the visual contrast to suit that of color film or digital sensors (which is much more limited than the contrast range of the human eye). This allows you to approximate lighting ratios and gain a better sense of how shadows and highlights will appear once recorded.
This viewing filter also features 37mm rear and front threads for attaching to other accessories or for attaching other additional filters directly to the viewing filter.
