Type 55 is very popular film that gives both negative and positive. You can google and find a lot of info. You want to carry a sodium sulfite solution (or washing aid solution) in a leak-proof tupperware if you want to peel the Polaroid in the field to see and keep the negative film for later use. You also want to give about one extra stop of exposure if you want good negative, but at that point the positive looks overexposed. You can't get both right at the correct exposure from one film, but the overexposed positive is good enough to confirm the composition while the correctly exposed negative is good for later printing. -- Ryuji Suzuki http://silvergrain.org
