Hi!
I want to do some enlargements from normal negatives to Cyanotypie-paper soon.
From what I've heard it's tricky with normal enlargers as the active ingriedient does only response to UV-light.
That means ultra long exposure times with normal light bulbs.
Any idea if there might be an cheap alternative to the normal light bulbs with higher UV content?

Doesn't work. People doing that make a internegative in intended size and then make a 1:1 cyanoprint
using a UV box with UV fluorescent tubes inside (or use sun - cheapest). Still takes some 10-30 minutes.
