The Wonderful World of Kodak IE

Hi folks, thought you might be interested:
All info. from Kodak Publication N-17:
"...Unlike the usual color film, the three emulsion layers
of this infrared film are sensitized to green, red, and
infrared rather than to blue, green, and red. A yellow
filter is used to withhold blue to which these layers are
also sensitive. When processed, a yellow positive image is
produced in the green-sensitive layer, a positive magenta
image is produced in red-sensitive layer and a cyan positive
image is produced in the infrared sensitive layer.
Blue can be formed in the transparency even though blue has
been excluded from the image by a yellow filter. Wherever
Magenta and Cyan are combined in the absence of yellow,
blue will result. (Note that the blue produced is not
related to any blue objects in the scene since this is a
"false-color" film.)
Numerous other colors can be formed, depending on the
proportions of green, red, and infrared reflected or
transmitted by the subject. As an example, healthy leaves
record red because they are "bright" in infrared; this
produces a light toned Cyan image which allows red from the
other layers to predominate."

I once photographed a billiard table, with an arrangement
of fresh Ivy leaves and White Carnations on top, illuminated
solely with candle light (three candles to be exact.)
Off-hand I can't remember how anything turned out except
that the Pool table's felt was blood red. Hmmm.....
