    IR film makes people look ghastly. What does this do?

  2. mizerock says:

    IR film was expensive, with VERY expensive developing. In theory, you should be able to duplicate the functions of speciality film with a digital camera, it just doesn’t seem to be as simple or as readily available as I hoped it would be.

    Yes, landscapes look surreal, sometimes amazing. I’ve also seen some great shots of NBA players taken with IR film. The guy used a flash, which normally isn’t allowed at games, but it was covered with an IR filter so it didn’t affect play. Especially interesting to be were the shots of tattoos on the dark skinned players, they were much easier to see in the IR spectrum.

    Oh! Here’s the article:

      IR film isn’t very expensive, $10 a roll; nor is it expensive to develop, you use the same chemicals as any other B&W film. The IR filters can be had on the cheap online as well.

    Bell & Howell has had these for some time on Amazon, for less than $90.

      No, they don’t have this particular camera. They have another. No idea which one is better.

      • YarbroughFair says:

        @tyger11, of course its different, that’s why it a Bell & Howell. They don’t use the term infrared in the product title but in the product description, it exactly what it is. And the pixes are much greater with the B&H model.

    Don’t forget, you can make GIANT IR FILTERS using a couple layers of Congo Blue theatrical gel. Humans see this filter as opaque black. IR cameras can’t see it, it’s transparent. Build some “They Live” alien propaganda signs which appear as shiny black squares to human eyes.

    Also, many black t-shirts are made with blue/black dyes, dyes which appear white in the near IR. Sharpie markers are carbon-black, and the writing appears black in the IR. Make your own IR t-shirt messages: http://amasci.com/amateur/irgoggA.html

  5. Bill Beaty says:

    The goggles, they do nothing! Lots of people are doing Congo Blue infrared projects, IR spotlights in particular. Google keywords: http://www.google.com/search?q=“congo+blue”+infrared

    While I think the line about seeing through clothes is a cheap sales tactic and I’m sure any image garnered that way will look awful. Should people have an expectation of privacy against having such images taken? Apparently the answer is a definite no if you are wanting to get on an airplane.

  7. buhbuhcuh says:

    Here’s an idea: get one of these, and hang out at the airport photographing TSA agents with it.

  8. Anonymous says:

    Does this work without the flash? is there enough ambient light inside? what about outside at night?

  9. Anonymous says:

    Or, instead, buy a cheapo disposable digital camera for $20, rip the IR filter off the CCD (it’s a freen piece of plastic), and put a piece of developed film in front of the lens.

  10. flipdingo says:

    The camera in the iphone does not have a pass filter and will take photos with an infrared filter in front of it.

  11. Victor Drath says:

    Huh. Thought I’ve read that it was illegal to sell point & shoots without an IR filter? Guess not. I can see some perv buying this and putting some black tape over the name in the corner.

    I’m a paranormal investigator and we use infrared to see between the uv lights that our eyes cant see and it picks up things we cant see. its a great tool to use in the investigations. But, you WILL NOT SEE THROUGH CLOTHES. It only blocks out the uv light and sees the light spectrum we cant see. thats all.

  13. bmc says:

    Any thoughts on using these low-end infrared cameras to detect heat leaks/insulation problems?

    High end energy audits use fancy IR cameras, and DIY folks try to use infrared guns instead, and map out the point measurements(*).

    Can anyone with such a camera try pointing it at your walls / ceilings / windows and let us know how well they can display heat gradients?

    • jimkirk says:

      Thermal imaging cameras like those made by Flir and Fluke use very long IR wavelengths, 8~15 micrometers. Night vision scopes and IR cameras use near infrared, 0.7 ~ 1.4 micrometers.

      Like ultraviolet A, B & C, IR has different regions with different uses and effects.

      http://en.wikipedia.org/wiki/Infrared#Different_regions_in_the_infrared

      The Flir i3 is only about $1200, quite cheap for thermal imaging. Still a lot more expensive than an Arduino servomotor controlled Melexis sensor…

      • Anonymous says:

        yeah, anything emitting black body radiation at wavelengths that this camera would see would probably burn you if you touched it.

  14. Scissorman says:

    If you remove the IR filter from a standard digital camera you really need to recalibrate the lens. They are a real pain to clean if you get a fingerprint on them.

    • Djhopscotch says:

      The lens doesn’t need calibration, the auto focus does. IR light doesn’t focus at the same point as visible light does. Some lenses have a dot to show how to correct focus for IR light.

    Nikon 5100 has a night vision feature. Does it mean it is also an infra red camera?

  16. DarthVain says:

    ya but does it come with flash?

  17. Gordon JC Pearce says:

    Some webcams use an IR filter as the first element in the lens, which can be carefully removed. Or, not so carefully in the case of my old Philips PWC680 webcam that I’ve had for about ten years, which got dropped. The rubber cushion fell off and it landed on its lens, dislodging the plastic ring that holds the IR filter on but leaving the rest of the lens intact – instant IR webcam!

    Colour neg film that has been completely exposed (ie. has turned black) is actually transparent to IR, so you can filter out all the visible light and only see IR.

  18. pidg says:

    I bought an excellent professionally-converted IR digital camera from Kolarivision (on eBay though). They basically take high-end compact cameras (e.g. Lumix), remove the IR filter, and replace it with one that passes IR.

    The main purpose of an IR camera is taking beautiful, striking photos of landscapes/architecture – skies frequently come out looking stunning.

    The “sees through clothes” thing is kinda true, but not really. It can see through very thin, close-fitting materials, which in my experience has only happened a couple of times, but then I don’t go out looking for that kind of shot.

  19. jjsaul says:

    Seeing forbidden nipples may be quite the selling point, but at that cheap, I’d be more interested in modding it for astrophotography if it can be remotely controlled through USB. What’s the diameter of the lens extension there? Less than 1.25″?

    I’m not yet ready to spend the money on a nice CCD, and not willing to have my Canon DSLR modified until I can afford to step up to better model. So that might be a fun way to screw around with a wider light spectrum on the cheap.

  20. durfsmurf says:

    Yes! I can’t wait to SEE through ANYTHING!
    Please rush me my exciting X-RAY SPECS

    I have enclosed $1.75 plus $.50 s/h.

    Allow 8 weeks for delivery.

  21. pidg says:

    Here’s a photo I took yesterday with my IR camera. Note the non-naked people.

    No idea if the cheap one from ThinkGeek could do quite as nice a shot, but who knows.

  22. milovoo says:

    There were also some interesting infrared links in an old ask.mefi thread.

  23. DavidInNJ says:

    I bought this camera about 2 weeks ago, it’s pretty cool. I think it’s a rebranded Yashica, but I’m not sure. I haven’t used it to see through clothes, so can’t speak about that.
