I've not used this before, though I assume all reference to 'film' really means prints (unlike type 55). I bought a couple of boxes of out-of-date stuff from Mr Cad in the UK & would appreciate any comments, feedback etc especially on stuff a few months out-of-date?
The biggest issue with out-of-date polaroid materials is the apparent drying of the chemical pack -- the goop that gets spread by the rollers. You'll see this as an incomplete picture -- the rollers just run out of chemicals to spread and there are white areas on the photograph. (particularly with opened boxes ..sealing them in something may help).
