More infrared pictures

Great news, I got the IR allowing filter and the camera works perfectly. This camera is extremely easy to take IR pictures with, since it has no IR blocking filter.
  1. Cut filter to cover lens
  2. Stick over lens, making sure no gaps (use black tape)
  3. Find a strong IR light source (incandescent bulbs produce about as much IR as visible light)
  4. Take pictures!
Also, it works with XP without installing anything! Can only take 640×480 pictures though.

All pictures: left, visible. Right, IR.
See how the pattern on the lowest cloth disappears in IR.

The brightness of the light (100W) looks the same under visible and IR, barring exposure changes.

You can see the lights on the camera.

I can finally take a picture of the whole note at once! Ok I gotta stop taking pictures of money.

It's interesting how ink is transparent to IR.

Lastly, this picture was taken in IR. The colour tint comes from some visible light getting through the filter. Fluorescent bulbs produce much less IR than incandescent.
