Hello, I am new to the forum, please be gentle with me. I have always shot on Fujichrome RDP 2 or 64T (Kodak) I really need a film i can use in low lighting levels that is faster than 100 ISO I can't find anything for 5 by 4 perhaps it simply does not exist. I usually push or pull the film, for this shot i am working on now i need two stops/stop and a half more than i can get out of the film. Does anyone know if there is any faster transparency film? Thanks your help is much appreciated.
