This E 15.- camera has the IR block filter in back of the lens. The sensor is not attached to the mother board, so it has to be held in place with a wrench (15) when unscrewing the lens, which is weakly glued to the 12 mm holder. It is possible to do this mod without detaching ribbon cables , as the inner frame can be tilted halfway out. I use the 2 filters from 3 D glasses: cyan and red, and an IR filter ( a plastic filter from Edmund optics, but an old floppy disk would work).
The filter can be permanently glued in back of the lens, but i decided to buy a 37 mm filter kit, with 10 mostly rather useless filters. The ring holding the glass can be removed with a putty knife ground to 37 mm width.

Another great source for infrared color photos: a Roscolux sample book of 200 filters, of which at least 50 - 80 filters are useful.

I ordered mine at Edmund Optical for about E 30, including shipping. Not bad for that many filters! It is thin plastic foil material, and each filter has a sheet with its own spectral curve in the visual range. Clicking on the color squares on their website even gives more info. Its purpose is illumination in dance halls, concerts and theatres.
Some results are more esthetic than others (green skies are ugly), which does not always says much about its scientific or practical value.
Additional useful filters are: Floppy dics, 2 crossed polaroid filters and , surprisingly, some ND filters. Obviously, many pigments seem to be transparent in the IR, and many surprises can be expected...){kind=link}

I often use an orange-red filter, handheld in from of the camera, from a scrapped enlarger. I do a white balance with the eye dropper tool in PS, Gimp or Lightzone, and swap the red and blue channel (plenty instructions on youtube) The orange filter allows some more color variety.
The cyan filter basically just swaps the red with IR, and allows all other colors to pass.
Wow that's cool if I put an IR Illuminator infront of my camera and solder it to a 9volt battery holder will this be able to get the camera to work during the night time?
