Canon 40D Infrared Photography Tests

We test the 40D with a Hoya R72 filter for infrared capability.
The Canon 40D (available from B&H Photo) is an impressive camera. But how does it handle infrared photography? For these tests we used a Hoya R72 filter on the camera and mounted it on a solid tripod and used a cable release.

The resulting images show that the 40D is capable of great IR photography provided you are in no hurry.

    Try your camera on manual exposure, setting the exposures from the article and then see. It sounds like you still have it on auto exposure.
