Type 672 - ISO 400
All of my Polaroid film is used in a Polaroid back for the Hasselblad - to check camera operation, and get rough ideas of exposure, composition and lighting.
At least that is the start. I have been known to occasionally scan the Polariod images and actually *use* them. Come to think of it ... a possible essay: "Images from the `Not-serious' Polaroid check exposures?"
Recently switched from Polapan Pro 100. 672 has the same exposure index as AgfaPan 400 - my "working" (most of the time... well some of the time) black and white film. Guess how many two-stops overexposed negatives I have.
