Re: Re: UV exposure light boxes/Solar plate

Jan,
I agree with you: those solarplates have a VERY steep curve. I'm using the
solarplates as a final product - because they can stand up to lots of
handling (I'm creating a photo installation for blind and visually impaired
students.) How much difference does the aquatint screen make in your
opinion?
