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. It also responds well to over- and under-exposure, and can be rated from EI 100-1600 for acceptable results with adequate processing. The film is coated on an anti-curl 100 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 roll of 120 format roll film.

Related Questions and Answers

Q: 1. How many exposures does this film have?

A: The amount of exposures on this Ilford Delta 400 120 film depends on the medium format camera it is used with. For example, using this on a Hasselblad 501CM which shoots in 6 x 6 cm format, you can get 12 exposures from this roll.

Q: 2. Red or infrared filters are necesary ?,or without it?

A: With the red filter it tends to give better definition and a bit less contrast which tends to be more pleasing to the eye I find. The filters are not necessary but they do help a bit.

Q: 3. Im ONLY 4 days into my Mamiya 645 1000s path,how do I know what films I can use in my camera,or,are all 120 films useable in the camera?

A: Any 120 film is compatible with the Mamiya 645 1000s.

Q: 4. Is this film PET based? I seem to be having a lot of problems trying to get it loaded into my Ars-Imago Lab Box.

A: According to Foma, the 120 roll film - a clear polyester base 0.1 mm thick, furnished with an anti halo color backing which will decolorize during processing.

Q: 5. What is the exposure latitude for Delta 400?

A: Slim. Not the most forgiving film. Meter like crazy.

Q: 6. Is the film on the black or white side?

A: I am not totally clear on your question. The film is a strip of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals on the back side.

Q: 7. What precautions if any I have to take before loading the IR film in the camera and also before I develop?

A: I would recommend loading it in a changing bag/tent if you are shooting 120. Many Rollei films are on a clear polyester base that has shown itself to behave like a light pipe and produce images that look like they were taken in a leaky camera. In fact, I would not open the mylar package the film comes in (inside the box) outside of the tent. I don't know if this IR film is on that clear base or not, but IR film and 120 spools are not a good combo, so I still recommend loading it in the darkest environment you can find.

Q: 8. I am loading the 120 size Rollei 400 infrared in a pinhole camera (6x6 size) but I don't see any frame numbers on the backing paper. Does it have any? If not, can you recommend how often to turn the film to the next frame?

A: Hey there brave soul of infrared endeavours! There are numbers on the film itself, pretty sure not on the backing. You will need to measure turns to get 6 centimeters. I would take strip of paper and measure 6cm on it and see how many turns will give you 6cm and a bit. Other than that, use complete darkness for loading/unloading too. Hope this helps :)

Q: 10. I have a canon camera 35mm eos rebel. will this film fit my camera?
