Here are the known infrared films. They dramatically differ in
the result due to spectral sensitivity. You can have information on
their features by reading the technical data:
Here, a comparison of three of the above listed films is given. The
pictures were all taken on a sunny day (late in the morning) and a red
filter was used. As it can be noted, from left to right the images
exhibit an increasing sensitivity to infrared light (actually, the
Ilford film is not properly an infrared film!). For a thorough
evaluation of infrared films have a look at this link.
