HELP I want to photograph far infrared (heat)

[stu_the_flat]

Hello

This is one for the boffins around here. I want to photograph or video heat for a project. now I know that most cameras will go down to near infrared and it is possible to use them for "nightvison" but i was wondering if there are any cameras on the market that can go down to 8–15 µm where the thermial raditation can be detected.

Cheers for any help you can provied.

No standard camera designed for 'normal' photography will go that low in wavelength. There are thermal imaging video cameras obviously, but I seem to remember the good ones (i.e. reasonable resolution) are the nasty side of £20k. You can rent them though. Google is your friend.

Canon made a variant of the 20D - the 20Da that had it's IR cut filter removed to make it more sensitive to IR (for astrophotography), also Fuji make (/ are making)version of the S5 Pro designed for police forensic work specifically designed for imaging under UV and IR (though don't know why).

probably not a wide enough range though 8o(

Your choice of film is important, too, and limited, I believe.
It sounds like you'll want to filter out all visible light, which I would imagine is not easy.
I did use some IR film in a bog-standard 35 mm many years ago; very interesting. I seem to remember London buses turned out green with yellow bonnets and grass was mauve.

A yes I see what you mean I have just found an item on sale and have been quoted £27,275

You could of course buy an infrared filter... like wot I did

Fantastic photos as always. That is shorter wavelenghts of infrared which is much like light. I want to record heat. But I don't think it is possable with out spending five figure sums of money.

I think that in order to record heat, it needs an actively cooled sensor. Makes sense really, otherwise it would be a bright emitter itself.
