Thanks Mel that's great.
Is the NPC back any better than the Hasselblad one? Mr Cad have got both types at the moment.
The Fuji instant film is rated at 100iso but that only seems to apply in midday sunlight.
In anything but ideal light, you'll need to adjust by quite a few stops, and I seem to get better results when it's developed in warm conditions.

The guy in the video mentions the reciprocity faiure.
He meters and takes a shot a 1 second which comes out totally underexposed. He then takes another for 5 seconds which comes out better, which is similar to my experience with the fuji fp-100c film.
They do a 3000iso B&W film as well but I haven't tried that yet.
