DIY Filter Pack: This is just a piece of "superblue" filter which you can use to turn your webcam or cheap point-and-shoot into an infrared camera. The filter allows you to take an infrared photo in the "red" channel of your camera, and a visible image in the "blue" channel. The
Public Lab kit comes with a white balance card and instructions on how install your filter -- it's pretty easy!
Infragram Webcam At one-twentieth the cost of normally priced consumer infrared cameras, this cheap but flexible device is designed for plugging directly into your laptop or integrating into other projects. It's also ideal for a Raspberry Pi, if you want to take it outdoors, do timelapse photography, or write scripts to control your camera. We're getting a company to fit 1000 standard webcams with infrablue filters, and shipping them as a bare circuit board with a USB cable - like an Arduino. You can make one of these yourself, although it seems that
not all webcams work, so be aware!
Infragram Point & Shoot: This is a straightforward, if basic, point-and-shoot camera which we're getting a factory to pre-convert with infrablue filters: you can simply take photos as you normally would, then upload them to our
free and open-source web app to quickly and easily get a variety of composite images and analyses (the site is currently in beta with minimal initial features). This isn't an SLR or even a particularly fully featured camera -- it likely won't have an LCD screen and may be "rebranded" with a Public Lab sticker -- but it's the new filter we've put inside which counts.

_**"The name "Infragram" comes from Infrared Photogrammetry, the use of photography to create spacialized and quantified data.** When NASA started using this technique on the Landsat satellites in the 1970's and 80's, each camera was custom-built for the purpose. Now, consumer cameras are so advanced that even a five year old point and shoot can generate excellent data with nothing more than a change of the filters and calibration through the Infragram site."_-- [Mathew Lippincott](http://publiclab.org/profile/mathew), Public Lab
_"We're excited that Public Laboratory is developing a low-cost infrared camera which will help us **track the success of wetland restoration projects in the Gulf Region--as well as help us track pollution.** The Gulf Restoration Network has been using the aerial monitoring techniques that Public Lab developed, so having the infrared camera available to put on the balloon and kite rig will only expand the applications of that technology as well as add value to airplane monitoring flights that help us watchdog the oil industry in the Gulf."_ -- [Scott Eustis](http://publiclab.org/profile/eustatic), M.S., Gulf Restoration Network

### Converting cameras
The question to start with is whether you can capture all the channels you need for your research question with a single converted camera or whether you should use a dual camera rig with one converted camera and one unconverted. That choice plays out in terms of what filter (blue or red) to use for converting your camera.
Check out this list of cameras, detailing how to convert some and collecting information on which cameras work and which don't:
* [Infragram-convertible cameras](/wiki/infragram-convertible-cameras)
Here's a link to a great video on converting a camera using PL's filter kit:

Please share your experiences and post additional cameras to this list!
### White balance
We've learned that careful white balancing of your converted Infragram camera is essential for good NDVI images. Learn how [in this short video](/notes/warren/08-15-2013/white-balancing-a-canon-camera-for-infragram-photography) and [read in depth on the topic in research by Chris Fastie](/notes/cfastie/06-17-2013/white-balance). There is also a wiki page on the subject at http://publiclab.org/wiki/infrablue-white-balance
### Filters
_Should you use a **RED** or **BLUE** filter?_
Early research by Public Lab contributors led to a blue filter technique for making Infragram cameras. But recent research on PublicLab.org has shown that red filters work better -- and on a wider range of cameras. Blue filters did not work on most CMOS cameras, especially cheaper webcams. By the beginning of the new year the Filter Kits will ship with red filters -- specifically the **Rosco #19 "Fire" filter** as well as the blue filter #2007.
### Coding Support
For those who use the webcam and have a Python interpreter, there are some image processing codes available at [Python Webcam Codes](/wiki/python-webcam-codes).

## Background
The Infragram camera was originally developed by Public Lab contributors to assess damage to wetlands [in the wake of the BP oil spill](/wiki/gulf-coast); but it's also a simple, easy-to-modify, open-source hardware and software tool that anyone who's curious about plant physiology and health can use. You can go back and read through much of this work by [reading research notes tagged with 'near-infrared-camera'](/tag/near-infrared-camera) and the most recent work on the Infragram technique by looking for [the tag 'infragram'](/tag/infragram).
Vineyards, large farms, and NASA all use near-infrared photography for assessment, usually by mounting expensive sensors on airplanes and satellites. **Infragram** brings this technology to average citizens, enabling them to monitor their environment through quantifiable, citizen-generated data.
Just as photography was instrumental to the rise of credible print journalism, DIY data collection technologies like **Infragram** set out to democratize and improve reporting about environmental impacts. By creating a low-cost camera and working with farmers and environmental activists, we hope to explore grassroots uses for this kind of technology.
