I backed a Kickstarter, the Publiclab Infragram the infrared photography project which developed a modified Mobius Action Cam with a 133 degree wide-angle lens, timelapse and still photography at a resolution of 2304 × 1536, and 1080p video. It is modified with a red filter and custom white balance. The camera comes with an SD card and standard 1/4-20 tripod mount.I added some fishing line, just to keep the fiddly lens cap attached.
Near-IR photography takes advantage of the fact that digital cameras are sensitive to IR and by removing the infrared-blocking filter and adding a specific blue filter the modified Mobius Action Cam filters out the red light, and measures infrared light in its place using that piece of carefully chosen "NGB" or "infrablue" filter.
The end result are these interesting blue-removed, IR-reflective and photosynthesis inferring photos. I've taken them from various angles in my front yard, with the Mobius and then with my iPhone5.

This kind of photography will allow for assessment of crops, keeping track of invasive species, and possibly even be used to scan for roaming bands of government agents tracking you down ...
