Key Features
- IR-Sensitive Panchromatic B&W Neg. Film
- ISO 400/27° without Filtration
- 650-750nm Infrared Sensitivity Range
- Very Wide Exposure Latitude
Rollei Infrared 400 is 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.

How would the camera's exposure / auto-metering be affected by using a fill-flash covered with a 720nm filter (as primary light source)?
I’ve used this film with a fully manual Zeiss camera with no metering capability. My best advice is to use a light meter app while stepping the ISO down by 4. So set the iso to 25 when using this film. Then take the shot. And I less you’re feeling really confident I’d bracket it 1/2 up and down.

Many people are saying that they're using a r72 IR filter. Why do you need this if the film is sensitive to only IR?
This film has a normal panchromatic + IR sensitivity range. It goes to 820 nm - the highest available I'm aware of. Some go to 750nm but that's lame IR. To record ONLY IR light (with quite dramatic results), you need to use an IR filter. I use a wratten 87. It filters out all visible light and only allows IR. Because IR light is in a small band on the EM spectrum, the film is rather slow. In broad daylight, I expose 4 seconds at f/8 with the 87 filter - but make your own tests. Hope this helps.

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

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?
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.

Do you need to load the camera in total darkness, like old Kodak IR film?
No, you do not need to load the Rollei Infrared 400 Black and White Negative Film in total darkness, but you should load it in subdued light. It can be loaded in most 35mm cameras under normal indoor lighting—just avoid direct sunlight or very bright conditions.
