I believe you are correct in this, as it mirrors my experience. The clue
for me was that as my exposures incresed beyound the minumum, as in doing
real "litho" work, the pinholes diminished significantly. Apparantly a
lot more light was either piping through the emulsion, or just going
through the dust.
