🎈 Public Lab: Revisions for 'Infragram'

Revisions for Infragram

122	warren	October 23, 2017 18:45 \| over 6 years ago The Infragram project brings together a range of different efforts to make Do-It-Yourself plant health comparisons possible with infrared photography. This project was made possible with support from Google and the AREN Project at NASA. Uses Vineyards, large farms, and NASA all use near-infrared photography for assessment, usually by mounting expensive sensors on airplanes and satellites. Infrared analysis is used for a variety of things, but most focus on assessing plant health, such as: to assess crops and #agricultural practices better #soil management (reducing #fertilizer, soil treatments) in #wetlands analysis Just as cell phone video has become instrumental in accountability today, we aim to democratize and improve reporting about environmental impacts. Getting started To start to do your own infrared analysis project, you'll need: Photos: A way to take near-infrared photos AND matching regular visible light photos from the same angle (in a single camera or two matched cameras) A question you'd like to answer -- look through these templates for how to design your analysis Software for processing and analysing your photos Analysis -- tips and support to interpret and understand what your images are telling you How it works Background In 2014, we launched an early version of this project on Kickstarter, and the video is a good overview of the project, although we've come a long way since: The Infragram Kickstarter video, a great introduction to the project. Infragram starter kits The Public Lab Store offers a range of Do-It-Yourself kits to convert cameras for infrared photography, as well as ready-made cameras like the Infragram Point & Shoot camera: Get a kit to start Comparing plant health An important limitation of most DIY techniques is that we are using uncalibrated cameras, and so the analysis works best when we compare two vegetated areas under the same conditions (light, angle, time of day) rather than just take a photo of a single region. That is, the DIY approach is based on relative, or comparative, uses -- you can't learn a lot without a point of comparison. [questions:ndvi-comparison] An easy way to do a comparison is: compare two areas (with the same type of plants) within a single photograph compare two photographs with the same camera settings and lighting conditions (angle, brightness, color), of the same plants [illustration] Learn more at Comparing Plant Health Troubleshooting making sure your camera is working (color balance, exposure, light source) what to compare against (see study design) different lighting conditions or angles [questions:infragram-troubleshooting] (older content below) Activities [activities:infragram] Getting started So 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 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 Here's a link to a great video on converting a camera using PL's filter kit: https://publiclab.org/notes/mathew/02-13-2014/great-infragram-conversion-video-canon-elph-130is 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 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 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. Blue or red filters Coding Support For those who use the webcam and have a Python interpreter, there are some image processing codes available at Python Webcam Codes. Give or get help Here 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! [questions:infragram] When describing your question or answer, please include details of the equipment and process you are using as described here for Infragram photos . Also see our older FAQ here: https://publiclab.org/wiki/infragram-faq Map Where are people doing Infragram work? This map will show some projects and posts by location: [map:tag:infragram:43:-71] Background The 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 information The Public Lab community has been building up a knowledge base in DIY infrared imaging for years.

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. Blue filters Currently 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 Support For those who use the webcam and have a Python interpreter, there are some image processing codes available at Python Webcam Codes.

This map will show some projects and posts by location: [map:tag:infragram:43:-71] Background The 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 information The Public Lab community has been building up a knowledge base in DIY infrared imaging for years.

118	warren	October 18, 2017 21:48 \| over 6 years ago The Infragram project brings together a range of different efforts to make Do-It-Yourself plant health comparisons possible with infrared photography. This project was made possible with support from Google and the AREN Project at NASA. Uses Vineyards, large farms, and NASA all use near-infrared photography for assessment, usually by mounting expensive sensors on airplanes and satellites. Infrared analysis is used for a variety of things, but most focus on assessing plant health, such as: to assess crops and #agricultural practices better #soil management (reducing #fertilizer, soil treatments) in #wetlands analysis Just as cell phone video has become instrumental in accountability today, we aim to democratize and improve reporting about environmental impacts. Getting started To start to do your own infrared analysis project, you'll need: Photos: A way to take near-infrared photos AND matching regular visible light photos from the same angle (in a single camera or two matched cameras) (#Getting+images) A question you'd like to answer -- look through these templates for how to design your analysis (#Study-design) Software for processing and analysing your photos (#Software) Analysis -- tips and support to interpret and understand what your images are telling you (#Analysis) How it works Background In 2014, we launched an early version of this project on Kickstarter, and the video is a good overview of the project, although we've come a long way since: The Infragram Kickstarter video, a great introduction to the project. Infragram starter kits The Public Lab Store offers a range of Do-It-Yourself kits to convert cameras for infrared photography, as well as ready-made cameras like the Infragram Point & Shoot camera: Get a kit to start Comparing plant health An important limitation of most DIY techniques is that we are using uncalibrated cameras, and so the analysis works best when we compare two vegetated areas under the same conditions (light, angle, time of day) rather than just take a photo of a single region. That is, the DIY approach is based on relative, or comparative, uses -- you can't learn a lot without a point of comparison. [questions:ndvi-comparison] An easy way to do a comparison is: compare two areas (with the same type of plants) within a single photograph compare two photographs with the same camera settings and lighting conditions (angle, brightness, color), of the same plants [illustration] Learn more at /wiki/comparing-plant-health (older content below) Activities [activities:infragram] Getting started So you have an Infragram camera, or a filter kit, and you want to start analyzing plant health?

It may tell you a) what areas of the photo are healthiest, or how healthy plants are in comparison to an equivalently-lit photo of another area of the same type of plant. If you could calibrate the images, you could compare across, or analyze a single image.

115	warren	October 18, 2017 16:14 \| over 6 years ago The Infragram project brings together a range of different efforts to make Do-It-Yourself plant health comparisons possible with infrared photography. This project was made possible with support from Google and the AREN Project at NASA. Uses Vineyards, large farms, and NASA all use near-infrared photography for assessment, usually by mounting expensive sensors on airplanes and satellites. Infrared analysis is used for a variety of things, but most focus on assessing plant health, such as: to assess crops and #agricultural practices better #soil management (reducing #fertilizer, soil treatments) in #wetlands analysis Just as cell phone video has become instrumental in accountability today, we aim to democratize and improve reporting about environmental impacts. Getting started To start to do your own infrared analysis project, you'll need: Photos: A way to take near-infrared photos AND matching regular visible light photos from the same angle (in a single camera or two matched cameras) (#Getting+images) A question you'd like to answer -- look through these templates for how to design your analysis (#Study-design) Software for processing and analysing your photos (#Software) Analysis -- tips and support to interpret and understand what your images are telling you (#Analysis) How it works Background In 2014, we launched an early version of this project on Kickstarter, and the video is a good overview of the project, although we've come a long way since: The Infragram Kickstarter video, a great introduction to the project.

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 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 Here's a link to a great video on converting a camera using PL's filter kit: https://publiclab.org/notes/mathew/02-13-2014/great-infragram-conversion-video-canon-elph-130is 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 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 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. Blue filters Currently 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 Support For those who use the webcam and have a Python interpreter, there are some image processing codes available at Python Webcam Codes.

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.

Map Where are people doing Infragram work? This map will show some projects and posts by location: [map:tag:infragram:43:-71] Background The 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 information The Public Lab community has been building up a knowledge base in DIY infrared imaging for years.

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.

[questions:infragram] When describing your question or answer, please include details of the equipment and process you are using as described here for Infragram photos . Background The 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 information The Public Lab community has been building up a knowledge base in DIY infrared imaging for years.

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.

Background The 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 information The Public Lab community has been building up a knowledge base in DIY infrared imaging for years.

103	natalie	December 16, 2014 19:55 \| over 9 years ago 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. Quick links Infragram.org, the free and open source web tool for processing your Infragram photos Infragram media images Recent Infragram research Infragram FAQ Infragram kit types You 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 started So 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 cameras 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 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 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 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. Blue filters Currently 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 Support For those who use the webcam and have a Python interpreter, there are some image processing codes available at Python Webcam Codes.
