Related Questions and Answers

Q: 1. 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: 2. 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: 3. What is the notch code for Rollei RPX 25 Black and White Negative Film 4x5 sheets?

A: The notch code for the Rollei RPX 25 Black and White Negative Film (4x5", 25 Sheets) is a V.

Q: 4. 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: 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. Can Rollei RPX 25 film be processed in Kodak XTOL developer? If not, do you have information on compatible developers?

Q: 7. 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: 8. What's the difference between rpx25 and rollei pan25 that was discontinued a few years ago?

A: It doesn't seem to be any difference as far as I can tell. There is no information online and after shooting both, there is no significant differences in the look.

Q: 9. Would anyone compare this with the late Agfapan 25 (APX 25)? Also, how well does this film do when processed with Rodinal/Adinal?

A: The film is very much like the old Agfapan 25. The film reacts about the same way to developers like Agfapan did.

Q: 10. 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.

A: The Rollei RPX 25 Black and White Negative Film (120 Roll Film) does have a tight curl. It takes some time to load it onto the reel.
