Anyone have any references on 'pulsed xenon' lamp sources for large format enlargers?
Ansel Adams mentions this in one of his Basic books, and I ran into someone's website once that built an enlarger with this source. I may have access to this technology thru work and want to start the learning curve to see if it's compatible with enlargment.
