Hi, There's a rain storm coming and a full moon tonight. I thought I'd try to photog raph the big puffing clouds lighted by the full moon. Later to double print & ex pose into a scenic. Any suggestions on exposure, film, or lens and f stop would be appreciated. I'm using a 4x5 Crown Graphic. Lenses available are 90mm,135mm,202mm and 250mm. (I'm thinking that the 250mm would give me the largest possible moon image). I h ave only Agfa 100 and TechPan 25. Thanks to all.
