Re: Polaroid 545 back

It's been so long I don't remember. I do recall, though, that there's a table of reciprocity corrections for different films in Steve Simmons' book on using the view camera.

  Bill, When you rate Type 55 at ISO 25, is there a need to calculate for reciprocity failure. If so, how do you do so? I've been using Type 55 with my Leonardo with some good results but I've just been guessing at the exposures. I'd appreciate any suggestions you have.

      The fact that you use readyloads in a polaoid back is entirely coincidental to the outcome. Polaroid type 55, exposed at ISO 25, will give you excellenmt B&W negatives. The new Kodak single sheet readyloads should work well also. The image size of the polaroid holder is a trifel smaller than the regular holder, but that's a minor point.
