Using Infrared camera, need info, see website

[boomer]

I had two stories about the infrared camera and how you could take photos of a cliff area or ridge and find where the earth has been disturbed.
But the kid cannot find them. does anyone have any idea on this. please read the following and give your advise on the subject. this may help us all. thanks, boomer

Infared Film

Hello Boomer,

I have used Kodak infared and color films but for a different purpose. You can get them in 35mm. The color film is used with a Wratten #9 filter ( yellow ) in daylight. I don't recall using any filter with the B&W type. I wasn't looking for treasure but there are pronounced color shifts in the photos that you can use to point out things such as spotting diseased trees in an orchard. By doing a series of test shots of known hidden excavations I think it would be possible to produce repeatable results that could then be compared to shots of a search area for possible similarities.
Handling infared is a bit as the film is sensitive to both heat and light so it must be kept cool. This can create potential problems with moisture condensing on the film but I had no problems. I kept it in a cooler till ready to use on site then made a changing bag using a thick coat. Have the camera and film ready to load and place it inside the chest area of the coat and fold the waist over to close the bottom off. Put your hands in the sleeves and load the film by touch ( practice this first ) being careful to avoid sunlight entering the coat amywhere. When finished rewind the roll and put it back in the cooler with the blue ice and keep it cool till delivered to the processor.
It has been 20 years at least since I used the stuff so there may be better methods by now.

Hey Boomer, USGS has IR sat photos of pretty much everywhere. These are high res shots and cost about $30. I have one of a nearby township, the whole township, and it is magnificent for what it reveals in detail re: old trails, otherwise invisible foundations and old formerly developed areas that are now under the plow. Don't know if this would help with your need for a shot of the cliff face, but it's out there if you're interested.

IR Film

It is true that the old Kodak IR Film was very temperature sensitive.
But the new film that came out last summer is not!
But! It is Very Light sensitive!
Some cameras in use today, cannot be used, because of this!
But!
My 40 year old Nikkon can be!
Just about anyone, who reads the instructions can use it!
It does require that you get it processed as soon as possible, tho!
