Really?

I saw this......

"........I am trying to find information about printing to transparency
and then using some kind of image reduction. From what I can tell it looks
like I would use a photographic enlarger........"





The suggestion of using the enlarger in reverse, effectively using it as a
camera is an interesting one but I'm not sure how well it would work in
practice - assuming one can get hold of a 4x5 enlarger.

It would probably work better to get hold of a 4x5 camera and photograph
your artwork and use the negative as your mask in the usual way.

(Yes I am aware that a 4x5 camera wouldn't produce a mask that would cover
a 4x5 board but neither would an enlarger)
