using infrared film in caves

[MichaelAngelo]

Just wondering, I still have some older 35 mm underwater cameras and was thinking of putting some of Kodaks high speed infrared 35 mm film in it to see what happens. Has anyone else tried infrared in caves? If so, what was the result? Can you even buy it in High Springs/Lake City/Gainesville area?

infrared film is an excellent way to find caves. Some Georgia caves were found by shooting infrared film in the winter from a plane.

is it available in the High Springs area? Its already Saturday and I doubt I'll get to a photo store by the time I fly Monday morning.

Michael,

Harmon’s Photo in Gainesville (a few different locations -- the largest stores being at Westgate Plaza at University Ave. and 34th Street and their Flair Lab south on 34th Street below Archer Road) used to stock black and white infrared film as well as color but that was "in the old days" before digital. I would call them to see but as far as I know that's your best bet for the Gainesville/High Springs area. And if they don't stock it anymore then call B and H in NYC and have them overnight some to you. Let me know how it works out...

I'm guessing that it might be neat in an air-filled cave but everything in an underwater cave would give off IR at nearly the same rate.

Just an educated guess though.

Shooting infrared with a normal camera (whether film or digital) does not = thermal IR. That is a totally different animal and requires much more expensive equipment.

What you would see with infrared film in a 35mm would be the reflected IR light. NOT the emitted thermal energy.

I've only dabbled with IR photography, but apparently some of the early digital cameras (i.e. Olympus 3040) are very good at capturing IR images. It can result in some very interesting photos, and you just need to add the proper filter.

Florida offers there DOQQs in infrared format. However, you can get fooled with coastal karst (been there) but you can find interesting things as well...

Here is a site with a lot of IR photography info.
