Q: 4. 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: 5. 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: 6. 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: 8. 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: 9. Would this film work for IR flash photography at night with an infrared flash?

A: Rollei Infrared 400 Black and White Negative Film (35mm Roll Film, 36 Exposures) is suitable for night photography with an infrared flash.

Q: 10. 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.
