This film is an enigma wrapped in a mystery concealed in a riddle. I purchased a very small stock of this rare film from a seller in Germany. The tins are labeled "Tura Pan Line Pancromatischer Documenten Microfilm" and it is a rare breed indeed. This film was marketed by a retailer in Canada as "Bluefire Police Film" and they produced a special developer for it which is now out of stock.

I have also seen separate references to this film being originally manufactured by Adox, Efke, Rollei & Agfa. I don't actually know if TURA is the manufacturer but since that's what's on the tins I bought, that's what I'm calling it.

In any case this is an ULTRA FINE GRAIN film. Some have written that it can be enlarged beyond the resolution limits of your lenses without losing grain detail. - It is certainly one of the finest-grain structured films I've ever seen aside from the super-slow lab films.

* I rated this film at ISO 10 and developed it using both Kodak HC-110 (B) and Rodinal 1:100 and I suspect you can get even better results and rate it at higher ISO speeds using other low-contrast developers such as POTA and Technidol.

In an experiment at the University of Southern Denmark, Dr. James Hoyland & colleagues used a microscope to show an exposed area of this film registering down to 10 microns! See Here.

So here's your chance to try out this mysterious film for yourself. I'm sure you'll have fun doing your own experiments. Get it while it lasts!

    I'm keeping these rolls inexpensive by re-using old film cassettes and sticking on an artsy label I've made just so you know what's inside. Using a bulk loader I made rolls of approximately 20 exposures each, sometimes a bit more or less and as with most bulk loaded film the very last picture of each roll will not be exposed as that is where it is taped. This is NOT a stock product from TURA and I am not proporting to represent that fine company in any manner. This film is NOT DX so you will need a camera which can be set manually.
