NIR Summer Experiences

During my summer holidays in the Pyrenees, I have made some experiments combining visible and NIR images taken with a modified 3M digital camera. As chlorophyll reflects very well the NIR radiation, my intention was to verify this phenomena using the same filters that we use for astronomy. The selected target was the vegetation of the hight mountain terrains to show how it invades the different altitude levels. The following pictures show together the visible and the NIR infrared images to better appreciate the differences.
