Rollei/Agfa's Ortho 25 is an orthochromatic black and white negative film optimized for technical, scientific, and half-tone work, as well as creative and pictorial applications. Characterized by extremely high sharpness and resolving power, this unique film also features an impressively fine grain structure and is also well-suited to reversal processing for black and white transparencies. Ortho 25 has a nominal sensitivity of ISO 25/15° and a high-sensitivity reserve of two stops for greater flexibility when shooting. Its spectral sensitivity ranges from 380-610nm and is suitable for photographing in either daylight or tungsten-lit conditions. The film's polyester base has been tested to an LE-500 (life expectancy 500 years) archival rating and also features anti-curling and anti-static coatings, as well as a special coating to promote smooth film transportation within the camera. Additionally, this clear base is particularly well-suited to scanning applications.

This item is one roll of 120-format roll film.

Q: 1. Is there any company that will develop infrared film?

A: IR film is developed with standard b/w chemistry, so yes. Any company that develops b/w.

Q: 2. Someone can informe me about the reciprocity of the Ilford Ortho Copy + 4x5? i want to use this film with a pinhole camera.

A: On page two of the following PDF, there is a graph that shows the amount of time you would need to add to various metered exposure times. http://bit.ly/1V4RhsS

Q: 3. 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: 4. What developer might produce the least bromide drag using a steel reel in a steel tank?

A: I would consider using Photographers' Formulary Pyrocat HD Film Developer (Dry) - Makes 10 Liters BH #PHPHDFD10L • MFR #01-5080 for this film. But for your bromide drag issue I would not use the stick agitation but rather inversion agitation to help with this issue so you get the chemistry moving well and it does not sit in one place too long causing the bromide build up in areas.

Q: 5. I'm developing this film in my darkroom. Usually I use T-max developer. What are you using to develop this film and any info on time and concentrate?

A: Per instructions inside box, I use D-76 developer at 1+1 dilution, 10:50 seconds development time. Great results with this film every time.

Q: 6. Does it work for an 80A Polaroid

A: Unfortunately the film for the Polaroid 80A was discontinued by the manufacturer in 1980. There are no more films made that are compatible with your camera.

Q: 7. any information on reciprocity?

A: I've shot a couple rolls, I like the images and I did a couple long exposures without compensating and all negatives were of normal density. However even though it's an ASA 25 film the grain is finer with Ilford Pan f 50.

Q: 8. Is there still a defect with the 120 format? There has been an issue with a defective backing
