Re: Attaching film in holders
Hi: Just in case you don't know there is a thicker type of CGP - CGP7 - it appears to be the same emulsion coated on a thicker base CGP 4 mil (0.004 in., 0.10 mm) CGP7 7 mil (0.007 in., 0.18 mm) See: http://graphics1.kodak.com/documents/TI_Camera_2000_CGP.pdf Kodak is also having CGP manufactured by a third party since June of 2007 - there may be some differences in the new version of CGP compared with the old. See http://graphics1.kodak.com/documents/Graphics Film Conversion.pdf Agfa also makes a film similar to CGP - Agfa Alliance CE - but its only availabe as 0.10 mm thickness - the same as the thinner CGP http://www.agfa.com/en/gs/products_services/all_products/alliance.jsp?p=3 Gord On Wednesday 16 April 2008 10:05:11 am Michael Healy wrote: > I'm going to work with my hand-crafted 7x17 camera again after a hiatus of > a couple of years.
