infrared and visual split image

The Canon A540 does leak some near-infrared radiation through its IR blocking filter. I placed a two layer filter of exposed and developed color negative film in front of the camera for the infrared image.

1/2s at f/2.6 for the near-IR image.
1/400s at f/4.0 for the normal image.
That's about nine stops difference.

P.S. Oh--here's a mouseover version.

This photo is really neat. I don't think that people tel lyou often enough that your photography is quite awesome.

I scared Nora with the mouse-over image.
