Zone VI sells six different Viewing Filters. There is a B&W version and a
Color version. The three models for B&W are as follows (the only difference
is the size of the viewing cut-out for use with a particular size film):
ZN5204 for 35mm,5x7, 2-1/4 x 3-1/4
ZN5208 for 2-1/4 x 2-1/4 (square)
ZN5200 for 2-1/4 x 2-3/4, 4x5, 8x10
For color, the models are:
ZN5206 for 35mm,5x7, 2-1/4 x 3-1/4
ZN5210 for 2-1/4 x 2-1/4 (square)
ZN5202 for 2-1/4 x 2-3/4, 4x5, 8x10
These are made out of series 90 Kodak wratten filter material, encased in
glass, mounted in a 3" black plastic frame with lanyard. The color version
is a different gel, more in tune with the higher contrast characterizes of
color film (their words.) They are $25 each (1996 catalog) and Zone VI
