Tiffen Variable Viewing 0.6 to 2.4 Filter (2 to 8 Stops)

The Tiffen Variable Viewing 0.6 to 2.4 Filter is designed to be held over a cinematographer or photographer's dominant eye and allows the primary effect of a neutral density filter to be conveniently previewed. By turning its rotatable front ring, this filter's 0.6 to 2.4 density reduces apparent exposure by 2 to 8 stops. Within that density range, different amounts of exposure reduction on a scene or image can be conveniently compared. The most desirable density can then be chosen, and using separately available lens filters, applied to a camera system with exposure settings that initially correspond to the amount of brightness perceived by the unaided eye.
