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.

This item contains one 36-exposure roll of 35mm film.

Related Questions and Answers

Q: 1. 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: 2. 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: 3. 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?

A: To get the full effect if IR, a filter is needed, that has always been the case. A deep red filter enhances the infrared effect.

Q: 4. 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: 5. Where do you send it for processing? Does it get processed as B&W film?

A: Definitely can develop as BW... I process the BW but I would vouch for The Darkroom Lab if you have anything complex or want high quality

Q: 6. 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: 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 developing time for this film using Kodak X-tol developer, I used hoya R72 filter

A: I don't know the effective reduction of your filter, but for an effective ASA of 50 a 1+1 dilution at 20 degrees C and a time of 7 1/2 minutes should suffice.

Q: 9. Has anyone out there worked with the old (discontinued) Kodak B&W infra red? I used to shoot it a lot back in the day and am wondering how this compares to it?

A: The Rollei Infrared 400 Black and White Negative Film (35mm Roll Film, 36 Exposures) is different than the old Kodak IR film. Unlike IR film the films today like this are sensitive to IR light. So, they do not have the full effect like IR film did. but it does give a good look like IR film.

Q: 10. 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.
