If you are in the field , you can put the neg into a zip lock baggie filled with water, and "clear the negative " with Hypo Clear once you get home . Polaroid instructions say you use Sodium Sulfite, but I once posted the same question on this list and couple others , and the consensus was to use Hypo Clear , wash, and hang to dry . If you are just looking to expose Type 55 to get a good print, that is usable for scanning and Photoshop , then stick to the EI 50 indicated by Polaroid, if you want a denser neg for printing , then use an EI of 25 . I use Type 55 a lot with my Santa Barbara Lensless 4X5 wide angle (2-1/2 inch fl ) and use exposures of about the 3-4 second range as a starting point , fine tuning if need be from there .
