10,000 ft on (108 rolls of 100'), Pan F plus/FP 4 plus/HP 5 plus. Ask them.
Gigabitfilm 40, 1-r. 3000, is available in lengths of 800, 400, 200, and 100 ft. Due to its 0,06 mm polyester base you can use the double lengths, so for example 800 ft in 400-ft magazines or 200' on 100' spools. $59 per 100'. Ask me.
Agfa Sound Track film 8 is available in 16, 2040 ft per roll. Agfa Color Positive film 30 in 16, 2000 ft per roll.

I'm glad that there are other manufacturers around the world. I'm surprised that there are some that manufactures black and white exclusively. Glad there's more option for those who wants to shoot in B&W, though.

Gigabitfilm 40, ISO 40 to daylight, was first used for cinematographic purposes in the 16mm format and processed on the 24th of January, 2005. Negatives out of the original developer have virtually no grain. Prints from Gigabitfilm originals on ordinary positive stock show their own grain structure, not that of the negatives.
When a shot is not perfectly focused, it shows. Gigabitfilm is like a mirror. I have not yet used it for prints.
I don’t have a scan and won’t order one soon because it’s impossible to display the film’s quality with pixels. It will only look like a video.
For the time being there is just hand processing with spiral reels. That’s the only way to handle this thinner material through the baths. Unfortunately I lost some time with the preparation of a new spiral reel based processing system. A 100-ft. and a 500-ft. reel shall be produced. The more serious interest I find the sooner I can come up with the first series. For more detailed information, please contact me via PM.

- Flexibility. Instant changes of processes, baths, temperature, time, and agitation
- Evenness. Every part of a portion undergoes the same conditions at the same time. Agitation can be much more thorough. The drying film can be viewed at a glance.
- Precision. Bath volume to film surface ratio can be kept to optimum at all times.
- Cleanliness. All parts can be kept clean way easier than with a machine.
- Security. Exact records can be made upon every single step in order to prove something to a customer. Pre-exposed samples (wedges or scales) may be processed together with each portion.
have a bottle of concentrate but no processor any more. If anybody feels the urge to enter that realm contact with Mr. Ludwig is advised. I think he will like to continue where we stopped. There is the one-shot formula for hand development and a machine formula for continuous replenishment.

OK, forget that, I didn't spot the missing w in your message.

Is there a website with info on this film stock?
The ciné section of Gigabitfilm so to speak zonked out. Mr. Ludwig could need some help with his English Marketing Department as well as the overall website entrance. I am in a new harbour now, mechanic workshop and film lab supply.
To sum up what you should know:
Gigabitfilm 40, ISO 40 to daylight, in 16mm is a panchromatically sensitized black-and-white thin-layer negative film. It is coated on colourless PETP of 0,06 mm thickness (2.4 mils), has an incorporated anti-halo protection that disappears during development, and a very effective antistatic agent on the back. Chemist Ludwig has developed a formula that allows to make negatives of varying contrast between 1:1 and 1:0.3 while maintaining maximum density of the layer. That is his special achievement with the result of about twelve stops exposure latitude. The characteristic curve doesn’t have the typical toe of a classic film but a rather sharp rise from nothing. It then pulls away in a linear fashion up to log 2.2 to bend until log 2.4. Gigabitfilm 40 plus original chemistry in that respect behave like a mid-19th century wet plate. Where you underexposed, the negative is blank. Exposure must be increased by 20 percent for times shorter than 1/500 second, by 50 percent for times shorter than 1/1000 second.
I have some 12,000 feet in stock, emulsion 2005-2. It’s perforated one edge, 0.3000". The film’s total thickness is an idea less than 0,07mm (2.75 mils). No marks or edge numbers nor codes.

I read somewhere about the amazingly fine grain of this film. Do you have any MTF charts? If I took a S16 Zeiss prime that shows a crisp 200lp/mm on the lens projector is the grain of the Gigabitfilm 40 so fine that I could see all of that on the processed negative?
Not looking to buy, just wondering, does the film stock get cheaper with volume. Are there set break points in price as volume goes up or is it a negotiation.
Can we call this film Gbf-40?
