Rollei/Agfa's RPX 25 is a low-speed panchromatic black and white negative film with a nominal sensitivity of ISO 25/15° in standard process and can effectively be pushed one stop with maintained results. The low speed also contributes to a very fine grain structure with very high sharpness. It features a traditional, thin emulsion and a transparent base, making it ideal for enlarging and scanning applications.

This item is one roll of 120 format roll film.

Q: 1. 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: 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: 5. 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: 6. 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: 7. 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: 8. how many exposures are on this roll?

A: 120 film has 12 exposures when used in a 6x6 camera. With other formats, it is dependent on the format of the camera to determine the number of exposures.

Q: 9. How is the curl when loading this film on reels? I find the retro 400 difficult to start and i've read the IR film is also.
