ND stands for "neutral density" - it is a filter type that (in theory) absorbs all wavelengths of the visible light by the same amount.

IR filters filter out all but certain wavelengths - the (near) IR wavelength of the filter. So basically, they are IR-pass filters, not IR-block filters. Thanks @TheLuckless!



As @Hueco states in his comment, IR filters will cut everything below a certain value. That value might be between 650 and 720nm - visible light, however, does go up to 750nm. Thanks for clarifying that, Hueco!

What you think of (white heat source, everything else red-ish) is most probably a thermographic camera - they differ from regular cameras in a lot of ways, including lenses that are (typically) made out of Germanium.

    It's important to note that most IR filters block somewhere between 650nm and 720nm and below. Important because visible light goes up to ~750nm.

  • lol. I just happened to start looking at getting a camera converted by the folks at life pixel (many hours spent researching this topic). I'm just not sure if I want to send in the 60D or get a cheap used Rebel for the job. I do love my film, but when it comes to IR shooting, digital wins hands down

  • While rare to find in the general photography world as a standalone piece, it is also good to keep in mind the existence of IR Block filters, as they are rather distinct from IR Pass filters. We might also want to highlight Near IR, as used in with "Infrared film", vs Far/Deep IR. [Which I think might be strictly digital for all practical purposes.] - Answer's original wording partially hides that they're both classed as part of IR Photograph.
