Rollei Infrared 400 is well suited for experimental, creative applications and for scientific photography. This film has a sensitivity up to 820nm and an ISO of 400 without filtering. Perfect exposures can be reached, using special infrared filters, leading to results with an unusual tonal range. Special AURA effects can be obtained by overexposing film. It has high contrast, very fine grain and excellent sharpness and is especially suited for scanning.
Please Note: To achieve strong Infrared (IR) effects we recommend exposing the film at a maximum of ISO 25 and using an R72 dark red infrared filter or deeper infrared filter. Standard Red 25A filters are not recommended. Individualized exposure testing is necessary to realize optimal results.
