Looking for pictoral (not Graphic Arts film) giant film, B & W, 11 x 14 and up. Prefer 14 x 17 or 16 x 20. For use on old Screen copy camera. ISO 400 or less, actually prefer 125 or even slower, would consider something like Tech Pan or other copy film that can be used pictorially. Apparently Ilford is cutting back on availability in this country, not sure I want to wait 8 weeks for something from Europe. Don't know about Kodak or others. Can someone out there help/advise on who carries this, brands, anything etc?
