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

The Public Lab community has been building up a knowledge base in DIY infrared imaging for years. To join in, check out these pages:
* **Infrared image processing,** specifically how to represent information that we can't see as images that we can see: http://publiclab.org/wiki/ndvi
* **The history of the project** -- the images below depict other prototypes that were created by our community over the years.

###Converting cameras
We'll soon be posting more information, but for now 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)
Please share your experiences and post additional cameras to this list!
A fantastic tutorial video on converting a Canon Elph 130IS camera by Dennis Baldwin is here:
###White balance
We've learned that careful white balancing of your converted Infragram camera can result in much better 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
If you have a Public Lab Infragram DIY Filter Kit, you'll also have [a QR code which we've printed](/system/images/photos/000/001/169/medium/1307649934001_l.jpg) which leads to "infragram.org". The idea, which has not yet been attempted, is to use the QR code both as a black/white contrast reference, and as a means to automatically white balance images which include the QR code, upon image uploading at Infragram.org. Please stay tuned, and chip in if you have ideas about this.
###Filters
The Infragram DIY Filter Kit ships with two different filters. This is because our research on which filter works best has evolved over time, but currently we believe that the #2007 is easier to use because it transmits more light, but the #74 transmits enough to get good results if you are careful with ISO and shutter speed. We think that the #74 should produce a more pure NIR channel, but this has not been measured (Research is continuing; please see [this series of research notes for more detail](/tag/infragram-filters), and post your results if you learn more about this.)
