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 135 µm-thick acetate base and also incorporates an anti-halation layer, which clears during development, for improved overall sharpness and highlight clarity.

This item is one 36-exposure roll of 35mm film, and its cartridge is DX-coded for ISO 400.

Q: 1. Will the outcome with a Lee #87 be comparable to a screw on r72 filter (Lee better with multiple lenses)?

A: Yes, I believe the 72 filter is just as good to use as the 87 filter. I hope that helps.

Q: 2. Can it be used as movie film for old 35mm motion picture camera?

A: Yes, this 100' Roll of Kodak Professional Tri-X 400 can be loaded in 35mm film cameras.

Q: 3. Can this film be developed in Ilford ILFOTEC DD-X Developer?What is the developing time using the Ilford ILFOTEC DD-X Developer? any recomendations?

A: Hi Ali,So far I have only used Kodak D-76 (1:1), I have been delighted with my results..I don't know if ILFOTEC DD-X compares with D-76.Good Luck enjoy the Film!!!

Q: 4. Is there any documentation about corrections to apply in case of reciprocity failure with times above 1 ?

A: Go to the Bergger website and download the data sheet. It is in there. 1 sec add 1/2 stop. 10 sec add 1.3 stops, 60 sec add 2 stops.

Q: 5. I have an old (1986) Minolta 35mm film camera. Will this film work in that camera?

A: The following Minolta cameras have an infrared film counter, which will fog (pre-expose) infrared film: Maxxum 70, 50, 7, 5, 4, 3, XTsi, HTsi, HTsi Plus, STsi, QTsi, 300si, 400si, 500si. Older Minolta cameras such as the SRT101 and similar mechanical cameras can be safely used with infrared film.

Q: 6. Where do you send it for processing? Does it get processed as B&W film?

A: Definitely can develop as BW... I process the BW but I would vouch for The Darkroom Lab if you have anything complex or want high quality

Q: 7. If you used an 850 IR filter with this film would you still get an image or would it just block all light?

A: Rollei infrared is only sensitive up to 850nm. So anything that's blocks 850nm and down prob won't produce an image. I use a Hoya 72 filter with this film.

Q: 8. Will this film be fogged by cameras which detect the DX coding using IR sensor (I have a canon A2)?

A: I do not believe the film will be fogged by DX sensor. I have used infraed in my Canon Elan 7 body with no issues. The one concern I did have was light intrusion through the rear of the camera at the film type window on the door. I addressed that concern by taping over the window. Also, load the film in low light. Do your research, the film requires certain filters (Red 25a) as I recall for strong IR response. The films reveals IR properties better at certain time of the year and day when UV light is stronger. Foliage reflects UV better when chlorophyll content is higher as I recall. Plenty of info on best way to shoot IR film online. Good luck!

Q: 9. What is the best filter to use to get full IR results?

A: Kodak used to make a great film called Kodak High Speed Infrared. Using a 25 A red or 87 infra red filter you could get beautiful white leaves on the trees without setting the ISO that low. The Rollei is nice film, but it's not high speed. A #87 filter will give you the most infrared look, but the ISO for the meter readings should be around 25, if not lower. Shoot a test roll and develop it and make sure to bracket at least a full stop in either direction.

Q: 10. I want to use Rollei Infrared 400 in a Pentax K1000. What l want to do is use it in a dark room with no light and l have a IR light attached to the camera. Do l need a filter ?

A: I wouldn't think you would need one since the IR filter is required to absorb visible light, which shouldn't exist in a dark room.
