Fujifilm FP-100B

FP-100B was Fujifilm's black-and-white peel-apart pack film, ISO 100, ten exposures per pack, image area 3.25 by 4.25 inches. It was built for the Polaroid Land 100-series cameras and 4x5 holders (Polaroid 405, Fuji PA-145) that ate Polaroid Type 664 and Type 665 for decades. When Polaroid stopped making their own peel-apart stocks in 2008, Fujifilm's FP line became the only peel-apart instant on the planet. That lasted a short time.

Fujifilm Japan announced the FP-100B discontinuation in September 2009 and production stopped in June 2010. The 4x5 sheet variant ended at the same time. The color sibling FP-100C survived until 2016, when Fujifilm killed peel-apart entirely. The closest current alternative is One Instant out of Vienna, which hand-builds a Type 100 peel-apart in small batches.

The character was clean panchromatic with good middle-tone separation, finer-grained than Polaroid Type 667 (the 3000-speed peel-apart it sat alongside) but flatter than Type 665, which was the only other studio-proofing stock with comparable resolution. Studio shooters loaded it when Polaroid backs on view cameras meant a quick check-peel-look before committing to Tri-X or HP5. Less pictorial output than pre-digital proofing. Still, the peel-print has a soft-shouldered look that some photographers built whole bodies of work around.

Unlike Polaroid Type 55, FP-100B did not produce a usable negative. The peel separated print from paper-mask waste. Positive plus negative in peel-apart form was Type 55 territory and is now no one's.

Availability is auction-only. Sealed packs trade for fifty to a hundred dollars each on eBay, and cold-stored stock past 2010 shows fog and contrast loss. Test before you commit.

Reciprocity exponent is 1.0. Zone Light Meter applies no correction past one second because none is needed: a metered two-second exposure stays two seconds at the print. For a stock used mostly in studio strobe and daylight, that is convenient. Trust the meter without math.
