The Infragram is an affordable, open source multispectral camera platform for measuring plant health.Developed collaboratively by the Public Lab community, it intended for home gardeners, hikers, makers, farmers, amateur scientists, teachers, artists, and anyone curious about the secret lives of plants! The Infragram Kickstarter video, a great introduction to the project.

Infragram kit typesYou can order pre-modified webcam or in the Public Lab store, or you can modify a camera yourself with a filter pack. Read more about the Infragram Point & Shoot camera here Getting startedSo you have an Infragram camera, or a filter kit, and you want to start analyzing plant health? After this page, the first place to look for answers is Public Lab's infrared photography discussion list, which you can sign up for in the left-hand column. There are plenty of other DIY infrared photographers, from novices to ""experts"", willing to offer advice and help troubleshoot.

We've learned that careful white balancing of your converted Infragram camera is essential for good NDVI images. Learn how in this short video and read in depth on the topic in research by Chris Fastie. There is also a wiki page on the subject at http://publiclab.org/wiki/infrablue-white-balance
FiltersShould 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. The Filter Kits now ship with red filters -- specifically the Rosco #19 "Fire" filter as well as the blue filter #2007. Blue filtersCurrently 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 until recently we believed that the #2007 was easier to use because it transmits more light, while 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. Coding SupportFor those who use the webcam and have a Python interpreter, there are some image processing codes available at Python Webcam Codes.

Keep in mind that we are a peer driven community and we encourage everyone to give as well as receive assistance and support!
When describing your question or answer, please include details of the equipment and process you are using as described here for Infragram photos . BackgroundThe Infragram camera was originally developed by Public Lab contributors to assess damage to wetlands in the wake of the BP oil spill; 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' and the most recent work on the Infragram technique by looking for the 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. What exactly is an Infragram camera?The Kickstarter project offered a few different versions:
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, 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, M.S., Gulf Restoration Network More informationThe Public Lab community has been building up a knowledge base in DIY infrared imaging for years.

The Infra-whatnow? The Infragram is a simple, affordable infrared camera platform -- developed collaboratively, by the Public Lab community -- for measuring plant health and geeking out on gardening. It's for home gardeners, hikers, makers, farmers, amateur ""scientists"", teachers, artists, and anyone curious about the secret lives of plants! The Infragram Kickstarter video, a great introduction to the project.
Quick links
Infragram kit typesYou can order pre-modified webcam or in the Public Lab store, or you can modify a camera yourself with a filter pack. Read more about the Infragram Point & Shoot camera here Getting startedSo you have an Infragram camera, or a filter kit, and you want to start analyzing plant health? After this page, the first place to look for answers is Public Lab's infrared photography discussion list, which you can sign up for in the left-hand column. There are plenty of other DIY infrared photographers, from novices to ""experts"", willing to offer advice and help troubleshoot.
Converting camerasWe'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: 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 and read in depth on the topic in research by Chris Fastie. 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 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.
FiltersThe 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, and post your results if you learn more about this.) Give or get helpHere are some resources to get help converting or using your Infragram camera. Keep in mind that we are a peer driven community and we encourage everyone to give as well as receive assistance and support!
When describing your question or answer, please include details of the equipment and process you are using as described here for Infragram photos . BackgroundThe Infragram camera was originally developed by Public Lab contributors to assess damage to wetlands in the wake of the BP oil spill; 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' and the most recent work on the Infragram technique by looking for the 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. What exactly is an Infragram camera?The Kickstarter project offered a few different versions:
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, 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, M.S., Gulf Restoration Network More informationThe Public Lab community has been building up a knowledge base in DIY infrared imaging for years.

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 Infragram Kickstarter video, a great introduction to the project.
The Infra-whatnow? The Infragram is a simple, affordable infrared camera platform -- developed collaboratively, by the Public Lab community -- for measuring plant health and geeking out on gardening. It's for home gardeners, hikers, makers, farmers, amateur scientists, teachers, artists, and anyone curious about the secret lives of plants! Quick links
Getting startedSo you have an Infragram camera, or a filter kit, and you want to start analyzing plant health? After this page, the first place to look for answers is Public Lab's infrared photography discussion list, which you can sign up for in the left-hand column. There are plenty of other DIY infrared photographers, from novices to experts, willing to offer advice and help troubleshoot.
Converting camerasWe'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: 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 can result in much better images. Learn how in this short video and read in depth on the topic in research by Chris Fastie. 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 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.
FiltersThe 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, and post your results if you learn more about this.) Give or get helpHere are some resources to get help converting or using your Infragram camera. Keep in mind that we are a peer driven community and we encourage everyone to give as well as receive assistance and support!
When describing your question or answer, please include details of the equipment and process you are using as described here for Infragram photos . BackgroundThe Infragram camera was originally developed by Public Lab contributors to assess damage to wetlands in the wake of the BP oil spill; 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' and the most recent work on the Infragram technique by looking for the 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. What exactly is an Infragram camera?The Kickstarter project offered a few different versions:
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!

The Infra-whatnow? The Infragram is a simple, affordable infrared camera platform -- developed collaboratively, by the Public Lab community -- for measuring plant health and geeking out on gardening. It's for home gardeners, hikers, makers, farmers, amateur scientists, teachers, artists, and anyone curious about the secret lives of plants! Quick links
Getting startedSo you have an Infragram camera, or a filter kit, and you want to start analyzing plant health? After this page, the first place to look for answers is Public Lab's infrared photography discussion list, which you can sign up for in the left-hand column. There are plenty of other DIY infrared photographers, from novices to experts, willing to offer advice and help troubleshoot.
Converting camerasWe'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: 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 can result in much better images. Learn how in this short video and read in depth on the topic in research by Chris Fastie. 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 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.
FiltersThe 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, and post your results if you learn more about this.) Give or get helpHere are some resources to get help converting or using your Infragram camera. Keep in mind that we are a peer driven community and we encourage everyone to give as well as receive assistance and support!
BackgroundThe Infragram camera was originally developed by Public Lab contributors to assess damage to wetlands in the wake of the BP oil spill; 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' and the most recent work on the Infragram technique by looking for the 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. What exactly is an Infragram camera?The Kickstarter project offered a few different versions:
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.
