I'm afraid that pinholes are a normal and expected problem with lith
film in its normal use, as ultra-high contrast copy material used to
introduce type or other graphic elements into photographs through double
printing, etc. I learned to use the stuff this way as an apprentice in a
commercial photo studio, and after shooting the copy and developing the
lith film, the invariable next step was careful opaque-ing of the
pinholes which invariably infested it. Not hard to spot pinholes on a
sharp-cut lith neg, but less fun when it's a continuous tone image. I've
been wondering about all these reports of successful use of lith
film--"where have all the pinholes gone?" I guess you've found
them.---Carl
