Kodak press release of the new Ektachrome IR emulsion
"Kodak Infrared Slide Film Broadens Imaging Spectrum For Creative
and Scientific Photography
New Orleans, LA, February 20-Kodak Professional today revealed the
first infrared-sensitive, color reversal film compatible with E-6 processing
chemistry. Previous versions of infrared-sensitive color slide film had to be
developed using process E-4 or process EA-5, but both processes were only
available from a limited number of specialty labs.
Now, thanks to a new forehardened film emulsion, scientists and
technologists who require a visual record of the infrared spectrum have the
option of processing their film locally or remaining with specialty labs. Kodak
predicts that the wider availability of E-6 processing should also increase use
among amateur and commercial photographers desiring a film for special effects.
The new Kodak Ektachrome professional infrared EIR film features fine
grain, medium sharpness and a 4-mil thick Estar base. It has normal sensitivity
to both ultraviolet and visible colors found between 380 and 700 nanometers, and
sensitivity to infrared radiation found between 700 and 900 nanometers. Kodak
Ektachrome professional infrared EIR film can be developed in either Process
AR-5 or Process E-6 depending upon the desired results. Photographs developed in
Process AR-5 will produce a more accurate record of infrared detail while
photographs developed using Process E-6 will produce images with higher color
saturation and contrast. Processing also affects film speed, with film developed
using Process E-6 exhibiting twice the speed of film developed using Process
AR-5. However, a fixed film speed and DX Coding cannot be applied to this film
because camera exposure meters are not calibrated for infrared radiation.
When using Kodak Ektachrome professional infrared EIR film in daylight
with a Kodak Wratten No.12 filter, a good starting point for film developed
using AR-5 is an exposure index of 100, or an E.I. of 200 for film using E-6. In
order to increase film speed, push processing is also possible with Process E-6.
As with earlier versions of Kodak infrared-sensitive slide films, Kodak
Ektachrome infrared EIR film requires special storage and handling. Since this
film is highly sensitive to storage temperature, freezer storage is recommended
for optimal sensitivity, although the film can be stored at 55 degrees for up to
a month without severe consequences. Loading and unloading should be performed
in total darkness and users should make certain that their labs avoid infrared
sources which may fog the film, such as sensors in the E-6 processor and night
vision goggles.
Kodak Ektachrome infrared EIR film can be exposed at shutter speeds
from 1/100 to 1/1000 without exposure compensation or additional filtration. It
will be available in 135mm 36 exposure rolls by June 1997. Prices are expected
to remain the same as previous versions for Process E-4 and AR-5. The Kodak
worldwide catalog number for this film is 144-8406.
