This is both of Pro4's Controlled Vignette filters for Square format cameras such as the Hasselblad 500 series or Bronica SQ.

The Low Key filter darkens progressively towards the edge, concentrating light into the focused subject in much the same way as old-master paintings, vignette contrast being controlled by lens aparture, Optimum aperture when used on a standard lens is f/5.6.
