Lowering ASA of BW Film
I have a 111mm f:1.5 Ektar large diameter lens without shutter or diaphram. I thought it would be fun to give film and lens long exposure times like old timers. My subjects are buildings , textures , my family and may be clouds.
I can access Ilford FP4 and Kodak Tri X 120 Products , D76 , Ilford Phenidone and may be most widely available chemical powders from a Istanbul Seller.
Is it possible to lower the ASAs of these films to 1, 5, or so. Is there a advantage ?
My new camera will be 120,6x10cms back.
