Infrared Filters On The Canon Powershot G12

I've got a Canon Powershot G12 that I paid to have modified so that infrared light can reach the sensor. Almost all digital cameras have internal filters to block infrared. I got just today a filter mount that allows me to put filters on the G12, so I experimented with dark red and infrared filters on it.

Cereus peruvianus (0833)
This is how the camera sees the Cereus peruvianus in my back yard with no filters at all. You can see a little bit of pale blue-green color comes through.

Cereus Peruvianus (0936)
When I switch the camera to black & white mode, you get this look, still unfiltered.

Cereus Peruvianus (0889)
Still in B&W mode but now with a dark red filter installed in front of the lens.

Bougainvillea (0917)
Same camera, same B&W mode, but now with an infrared filter mounted instead of dark red. Obviously not the Cereus peruvianus this time. The plant near the lens is a bougainvillea in bloom. I somehow did not photograph the cactus again in true infrared. Maybe tomorrow, if it's sunny.
