Characterized by a unique dual emulsion design, Bergger Pancro 400 is a high-speed panchromatic black and white negative film featuring a nominal sensitivity of ISO 400/27° and a wide exposure latitude. By employing both silver bromide and silver iodide emulsion layers, an organic grain structure is provided that results in natural tonal gradations and an overall fine grain quality for high-resolution, well-detailed results in a variety of lighting conditions. The film is coated on an anti-curl 175 µm-thick polyester base and also incorporates an anti-halation layer, which clears during development, for improved overall sharpness and highlight clarity.

This item is one box of 25 sheets of 8 x 10" black and white negative film.

Q: 3. Is it OK to process in D 76, if so would 1:1 or stock be best?

A: D 76 is an excellent all purpose developer and would work fine. However, you may want to consider other ones based on the type of film. Ilford's Delta films and Kodak's T-Max films have T grain emulsions. They are considered the newer type of films and therefore have newer developers. TMax dev made by Kodak and I can't remember the Ilford version (DD something???) are specifically designed to work with T grains. Older emulsions like Kodak Tri-x or Ilford's HP-5 work better with D 76 (older developer). I personally have worked with Delta films and Xtol developer from Kodak and got great results. Other people that I know have used D 76 and it worked for them, but I was more impressed with the tonal and grain nature of Delta/Xtol. As far as 1:1 dilution or stock, I always dilute unless I need a faster developing time. It's more economical and not as critical on the time. I also use it 1:1 as a one shot developer and chuck it out after I use it. This gives me more consistent results. Finally, there is a web site called Digital Truth Photo that lists every film, every developer and a ton of film developer combinations/temperatures/dilution. It's got it all. Good luck.

Q: 5. please late me know the expiry date.?

A: B&H buys and sells paper in bulk. In general we regularly maintain fresh paper stock. All of our paper is at least 6 months from expiration (typically much longer). Anytime film stock is less than 6 months from expiration we sell it in a separate section and label it as short-dated and also price it with a slight discount (again due to the volumes we sell this rarely occurs). Unfortunately we do not have access to our inventory to hand inspect the expiration date of any of our papers prior to purchase.
