Infrared film for heat loss measurements on a home

[Kolesar]

Hello all. I would like to buy a roll of film to photograph my house to see where the heat losses are. Does anybody have the answer of:
1. What type of IR film should I buy? I don't want overlap with visible light, though I'll shoot at night.
2. Can I use my point and shoot camera, or do I have to borrow an SLR that a friend last used in used since 1998? It probably has the focal point for IR marked on the lens.
3. Develop...where? I always send my color print film to www.mysticcolorlab.com Their website does not mention any black and white developing. Is IR C-41? Mystic says they will do "other films", like Seattle Film Works type, which is not C-41.

I googled this subject and got lost in the details of artistic IR photography. I am just looking for a wholesale recommendation like: "order __________ and take it to ______ developer. My favorite photo store where I used to buy my print film disappeared last year and now all that I have left is Ritz or Dodd's Camera, which are commodity shops. Thanks

1. This is just a wild shot, here, but

You might contact your electric company and see if they have any suggestions about how to shoot and where to get it developed. It seems to me a few years ago PG&E in CA was doing that sort of thing.

Also, check phone book. In larger cities there are always private photo labs. Even my little town of Napa has a couple of photographer-run private labs.

2. That's a good idea

I was hoping just to "wing it" and pull it off in a matter of minutes. I had a friend who shot some decades ago, but I am sure the films have changed since then. Thanks

3. IR film responds in visible light frequencies

I need a total-IR blackout filter (87?) and all I have is a 25A filter that is red. I expect that headlights and starlight would reflect off the house and ruin the shot. My exposures would be on the order of an hour, I expect.

Well, maybe next year.

4. After a little browsing, I don't think it's possible

Infrared film can be exposed by heat, but the heat needed is not a typical heat. Some objects heated to temperatures in excess of 482-932 degrees Fahrenheit will give off an infrared radiation. These can be captured on film to differentiate heat in metal parts heated by use, as in an engine. You can also use heated metals to expose objects. This can be captured on film with long exposures.

Trying to capture heat loss in a house or human heat with infrared film is impossible. Systems with liquid crystal sensing devices are needed for this application. These systems then convert the information to be visible and output it onto a video screen or hard copy. This is electronic thermography. Electronic thermography can differentiate human heat and simulate those special effects in the movies that incorrectly refer to it as infrared photography.

I've heard that I can use infrared film to detect heat loss from my house. How do I accomplish that?
The sensitivity of infrared photographic films does not come anywhere near the part of the energy spectrum emitted by heat escaping through windows or doors. The advertisements for windows and insulation you may have seen 'using infrared photography' to show this effect were probably made with electronic thermography, which is a system that converts different infrared signals into a computer screen display. This display can then be photographed using conventional photographic film.

I think you need one of these to do the job:
