Actually, you would need several pinholes.  I often use my view camera
with pinhole and need to use pinholes of different sizes to accommodate
the varying pinhole to film plane distance.  This distance determines
the size of the pinhole.  There is a rather expensive "view" pinhole
camera available with a disk that can be rotated to select these
different sizes.  I believe that it costs around $1,000, but I have
several lens holders that I swap out to do the same thing.
