more on amberlith/rubylith



With more than 30 minute exposures, the amberlith will transmit enough
light to expose a Pt/Pd coating.  For the records, I had a three hour
exposure.  One of my folding axis prints with lots of highlights.  The
third print in the examples of these prints of my web site.  Don't have
any rubylith.

Looks like time for that black masking tape.
