There is no separable negative like you get with 55 or 665.

The 100 stuff is 100, bang on the money in my experience. It is excellent proofing material. I have also been impressed with the colour 100, the 400, the 3000, all of them seem to rate [almost] exactly at box speed. Actually there is much less ambiguity on this than with the Polaroid films. I also found it a nuisance with polaroid to have to convert an ISO 80 proof to an ISO 100 exposure etc.

Long exposures: I have done seconds to many seconds with 400b and 3000b with no apparent problems. My attitude on that is kind of blase, though; if I don't get what I want I just dial in a longer exposure and reshoot. Matching reciprocities could be computed, in principle. Anyway I think I've done ~8 sec exposures with 3000b (pinhole!) and also some rather long, multisecond exposures with the fp100c, no problems. I don't recall trying fp100b over more than a second or two but certainly ~ 1 second should be no problem. Short answer: no guarantees, but I think you will be very pleasantly surprised.
