There is some pretty interesting stuff out there on colors.

I saw Kevin Price from KSU and his research on telematics. They took a camera and took the infrared filter off and tied it onto a model airplane with a GPS and coursed it's flight over fields. They then put some filters on it to show variations in biomass. They then used some software to link all the pictures together and offset perspective and end up with a mosaic of the field with a resolution down to 1 sq inch.

Anyway Price went through the infrared filters and how they work with different pictures. It's amazing what you can see when you filter out noise of different colors. They had a picture of a soybean in which half was healthy and half had some disease. They didn't look that bad to the naked eye, but when you look at it in infrared, it was drastic. The disease took out so much of the biomass it looked really bad.

I'll try to see if I can find the presentation, but it was fascinating to see what just changing the spectrum does.
