Rollei Infrared 400 Black and White Film 35mmis a unique infrared-sensitized panchromatic black and white negative film with a nominal sensitivity of ISO 400/27° without filtration. It is sensitive to IR wavelengths within the range of 650-750nm and can be used to produce unique halation effects with filtration and by varying the exposure length. It is suitable for working in both daylight and tungsten conditions and is characterized by a fine grain structure, notable sharpness, and high resolving power. Additionally, a good contrast profile offers clear separation between shadow and highlight regions. The film's polyester base has been tested to an LE-500 (life expectancy of 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 contains one 36-exposure roll of 35mm film.

Related Questions and Answers

Q: 1. Given that this film is less sensitive to IR light than visible light, what ASA should it be shot at for infrared photography?

A: It depends on the filter you use with the Rollei Infrared 400 Black and White Negative Film (35mm Roll Film, 36 Exposures). Some say, exposing the film at a maximum of ISO 25 and using an R72 dark red infrared filter or deeper infrared filter. Note it takes experimentation and trial and error

Q: 2. 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: 3. Do yoh use a standard development process for this film?

A: Yes; to be exact, I use D-76.

Q: 4. 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: 5. How would the camera's exposure / auto-metering be affected by using a fill-flash covered with a 720nm filter (as primary light source)?

A: The exposure would be cut down by quite a bit. It doesn't make sense to shoot in auto. You will have to shoot in manual mode and test by trial and error.

Q: 6. Will 4x5 IR film work in a pinhole camera?

A: The Rollei Infrared 400 Black and White Negative Film (4 x 5", 25 Sheets) can be used in a pinhole camera.

Q: 7. 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.

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. Is this film sensitive to the wavelenhth at Hydrogen Alpha (656.281 nm) what are its reciprocity characteristics and is it generally useful for astrophotography?

A: Rollei INFRARED has an infrared range of (650 – 750nm). According to Rollei, the reciprocity is 1.43. IR film needs IR light which is more available during the day. Shooting it at night would be experimental.

Q: 10. Do this have a notch for identifing the emulsion side?

A: Rollei Infrared 400 Black and White Negative Film (4 x 5", 25 Sheets) does have a notch for identifying the emulsion side.
