Description

Photos of the eastern shore of Lake Huron from a commercial airliner using three cameras: a Canon A810 with the IR block filter replaced with Rosco #74 blue filter (Infrablue), an unmodified Canon S95 (RGB), and a Canon A495 with the IR block filter replaced with a Wratten 87 filter (NIR).
Rayleigh scattering of shorter wavelengths make the blue channels hazier, except in the NIR image in which all channels are purely near infrared light. The red channel is primarily near infrared light in the infrablue photo, primarily visible red light in the RGB photo, and all near infrared light in the NIR photo (the Wratten 87 filter passes almost no visible light). The NRG image is made from the infrablue photo and is really NBG. By stretching the histogram of the infrablue photo (Photoshop/levels), the range of NDVI values with distance is reduced (the gradient becomes steeper?).
