I have heard of gas hypersensitizing process a long time ago, and I too have
been looking at how to acquire the films, is this something you must do
yourself, (the hypersensitizing ) or are the films available at retail source
or outlet ? I know of one photographer (Stephen DiRado ) who has works posted
on a web site, he does night photography, and from what I can tell he must
use the gas hypersensitized films . If any one is interested in obtaining the
URL for his works, they can email me off list
