instant. This are one of the first I shoot with my Mamiya RZ 67 and a Polaroid back some years ago. Fuji FP-300B and I like the tonality, to bad that all black and white pack films are gone and out of production. I have a bunch stored up in my cooler and are waiting for some New55 4×5 to come so there will be more B&W instants but only if we buy and use whats coming, I will buy and us as soon as they are in production. I did support the Kickstarter campaign so I will have film from the first shipping at least.
