playing some more with the IR filter I have

Which IR filter do you have? You're not getting much effect here. The agave plant down in front is very grey for a IR image. So is the pine tree. One way to see the affects is to shoot more plant life. Contrast that with water in the scene. The water should be black while the foliage should turn white.

It's a great old car. Houses and cars just don't have any reflected IR light.
