In reply to the ND filter thread.
I was playing with an old Polaroid 110b folding camera last night.
It has a flip up lens cover which incorporates an approx. 2mm pinhole .
The Rodenstock lens ranges from f4.7 to f45.When a faster film is used,you 
are instructed to flip up the lens cover w/pinhole and shoot with the 
aperture diaphragm wide open.The pinhole f stop becomes f90.
This might be an easier solution for the person hunting for large  ND 
filters.
