efke IR820 Infra Red
The efke IR820 Infra Red film is a true Infra Red film with extended spectral sensitivity to 820nm rated at a nominal 100 ISO without filter. Recording Infra Red radiation creates unworldly artistic effects, clouds, foliage and warm skin tones appear white while blue sky and water black. Most panchromatic films are sensitive to light wavelengths from about 400nm- 700nm, which is enough to record what the eye can see. Longer wavelengths are invisible to the eye but not to this film: its Extended Spectral Sensitivity enables it to record wavelengths as long as 820nm, well into the Infra Red.
To get the best results, a filter is needed; deep red or special Infra Red filters block out the visible portion of the spectrum letting the IR wavelengths pass to be recorded on the film. The deeper filter the more of the visible is blocked, but exposure times increase and with very dark IR filters it is not possible to use camera metering. Using a Heliopan 665 filter results in a reasonable balance between usable film ISO, so you can even expose handheld, recording Infra Red with sufficient of the visible spectrum blocked with the ability to still use camera metering. A Heliopan 715 will give much increased Infra Red being recorded but with extended exposure times and the need to determine exposure manually.

Product Details:
BECAUSE YOU ASKED FOR IT!
Freestyle has partnered with Fotokemika to bring you Efke IR820 (true infrared) film in multiple formats!
This is the exact same formulation you knew as Maco IR820c Precision Infrared film. It has a spectral sensitivity up to 820nm and available in a variety of formats including 35mm, 120 size, 127 size, 4x5, 5x7 and 8x10.
When used with filters that are deep to opaque red it is effective in creating scenes where foliage and clouds are pure-white, while water and blue sky is coal black.
Warm skin tones and lips will appear white. It has infrared spectral sensitivity up to 820nm.
Note: Testing of this brand new emulsion has shown that best results are obtained by exposing the film at ISO 25 and using an infrared filter such as a Hoya R72, Tiffen #87 or B+W 092.(Standard Red 25A filters are not recommended).
