If you're looking for a cool new way to capture and process infrared/near-infrared photos, consider the Raspberry Pi NoiR along with Public Lab Infrared photography kit and infragram processing tools.HooperFly was instrumental in providing the lifting platform for the acquired images mentioned in the article. Thanks to the Public Lab folks for including us in on the fun. Check out the Raspberry Pi article for all the details. Multirotors at work.

this camera with blue filter?
ok so how does one use Rasberry pi and NOIR to do this?..yeah im a ultra noob
thanks for the writeup. I wrote up my notes for scripting the Raspberry Pi to boot into timelapse mode here. Here's the image processed in NGB (Near infrared, Blue, Green) and NDVI through Infragram.org:
Haha, I read that just as I woke up... But I get you now!
Well, you can try scratching it off (!) your sensor. Or shell out $8K for a Leica M Monochrom ;)
This isn't a problem for me, I removed several IR filters ;-). My suggestion is remove the other filter called Bayer, this bayer filter divide the visible spectrum on three primary colors (RGB), I'd like have a monocromatic camera without any filter.
@Daniel Yup, removing the low-pass filter requites a little bit of surgery :)
It is usually a sheet of glass very close to the sensor.
That's great¡, no more camera modifications. But for vegetation survey could be beter if not only remove de IR filter and add a new rossco filter. The better option would remove the bayer filter and only capture one channel, we could obtain any wavelenght playing with external filters, and mount a array of several cameras like tetracam ADC Lite. But I don´t know remove the bayer filter, I think it is embebed on sensor.
