Digital BW, The Print

Yes! But like you, I didn't notice at first which side was which. You can't
really tell by sight, but by touch. Rub a dry finger on each side, one side
is definitely rougher...

...and that is the side that needs to go on the film.

Another way I found is to have the lid (of the scanner) open with the lamp
on, place the AN glass on the Scanner glass - wrong way up - bucket loads of
shiny newton-rings cannily lit by the lamp. When it's right way up... no
bnasty rings to be seen.

Hope this is helpful,

nij
