Thanks people. Well I have some on the way to me in the post, and hopefully it will be useful!
The specs sheet claims:
KODAK HAWKEYE Surveillance Film is a continuous
tone, black-and-white panchromatic film with extended red
sensitivity created for traffic surveillance recording.
HAWKEYE Surveillance Film is intended for exposure
under daylight, artificial light, or red filtration in night flash
applications.
This film features high speed, wide exposure latitude, and
a wide contrast range, especially compared to other films
intended for this application. Excellent sharpness, resolving
power characteristics, and extremely fine grain allow a high
degree of enlargement.
It sounds interesting. I wonder what effect the extended red sensitivity will have?
