We are learning more about infrared photgraphy from experience. The camera doesn't record light as we see it, and the colours are arbitrary based on different wavelenghts of infrared light. In this picture, the dramatic sky was barely noticable to the human eye. This is a wonderful image for a large monitor.
The camera recorded the following information in the original image file:
