The Infragram Point & Shoot is a handheld, battery powered mini camera (a modified Mobius Action Cam) for doing plant analysis. We modify these to replace the infrared-blocking filter with a red filter, effectively exchanging its blue light channel for infrared light. (Lead image by @mathew) This is based on a great deal of research by Public Lab contributors and was initially pioneered in our community by @nedhorning and @cfastie. See especially these two research notes. Also see this page for how to do this with a Raspberry Pi camera. WhyVineyards, large farms, and NASA all use near-infrared photography for assessing plant health, usually by mounting expensive sensors on airplanes and satellites. At Public Lab, we've developed a Do-It-Yourself way to take these kinds of photos, enabling us to monitor our environment through quantifiable data. Read more about the Infragram project here.
Our technique uses a modified digital camera to capture near-infrared and red light in the same image, but in different color channels. We then post-process the image (see Infragram.org, below) to attempt to infer how much plants are photosynthesizing. This allows us to better understand and quantify how much of the available light plants are using to produce sugar via photosynthesis. BasicsBefore you begin, to take useful plant analysis photos, you'll have to modify your camera's white balance, so that vegetation looks "bluish" but there is not an overall red tinge to the images. You can achieve this with a custom config file, as described below. Some cameras may require a firmware upgrade to v1.20. If you've gotten your Infragram Point & Shoot from the Public Lab store, both the config file and the v1.20 firmware should be on the SD card provided. However, you'll still have to load up the white balance configuration as described in the Activities section below.

An incorrectly white-balanced image such as the "BAD" example below may appear with an overall reddish tint. This means the camera probably has not accepted your config file, possibly due to misformatting or incorrect uploading.

You can achieve this with a custom config file, as described below. Some cameras may require a firmware upgrade to v1.20. If you've gotten your Infragram Point & Shoot from Public Lab's Kits initiative (through Kickstarter or the Public Lab store), both the config file and the v1.20 firmware should be on the SD card provided (in addition to this documentation!). However, you'll still have to load up the white balance file as described in "Installing config file" below.

An up-to-date version of this documentation will always be available on this page The Infragram Point & Shoot is a handheld, battery powered mini camera (a modified Mobius Action Cam) for doing plant analysis. It has been modified at the factory to replace its infrared-blocking filter with a red filter, effectively exchanging its blue light channel for infrared light. This is based on a great deal of research by Public Lab contributors and was initially pioneered in our community by @nedhorning and @cfastie. See especially these two research notes. Vineyards, large farms, and NASA all use near-infrared photography for assessing plant health, usually by mounting expensive sensors on airplanes and satellites. At Public Lab, we've developed a Do-It-Yourself way to take these kinds of photos, enabling us to monitor our environment through quantifiable data.
Our technique uses a modified digital camera to capture near-infrared and red light in the same image, but in different color channels. We then post-process the image to attempt to infer how much plants are photosynthesizing. This allows us to better understand and quantify how much of the available light plants are using to produce sugar via photosynthesis.

This means the camera probably has not accepted your config file, possibly due to misformatting or incorrect uploading.
AssemblyTo install the IR lens (or any lens) into a Mobius camera, you will need the camera, your new lens, a size 0 philips screwdriver and a small hex screwdriver.
In order to begin disassembling the camera, flip it over. You will see two screws at the corners of the camera on the side nearer to the lens.
Loosen the two screws thoroughly. They may not come out, and you don't really want them to come out because they are small and easy to lose. If you loosen them enough, you can remove the back casing from the camera without needing to take them all the way out.
At this point you can see the lens. The lens is only attached to the ribbon, so you can use finger strength to remove it and get access to the screws that hold it on. There are two screws holding the lens to the camera.
You can remove both of these screws with the screwdriver BE CAREFUL The screws are small and very easy to lose. Place them somewhere safe, clean, and away from your working area. You may want to use play doh to hold them, as jewelers do.
Once you have removed the screws and placed them safely, you will find the lens cannot yet be unscrewed. This is because there is a hex screw holding the lens in place, preventing you from removing it. Use the hex screwdriver to remove it.
BE CAREFUL The hex screw is also extremely small and can easily be lost. Put it in a safe place! Once you have removed the hex screw, you can use your fingers to unscrew the lens. It may be difficult to get started, but fingers are a good tool to use for this.
Remove the old lens and replace it with your new lens, then replace everything how it was sequentially. You may need to focus your lens. To do that, see this guide written by cfastie Installing config fileIf your camera did not ship with a config file or you are using a new SD card, follow these steps to get your Infragram Point & Shoot to take properly white-balanced images, necessary for post processing at Infragram.org.

If you've gotten your Infragram Point & Shoot from Public Lab's Kits initiative (through Kickstarter or the Public Lab store), both the config file and the v1.20 firmware should be on the SD card provided (in addition to this documentation!). However, you'll still have to load up the white balance file as described in "Installing config file" below. TroubleshootingIf you have trouble, please post on this site or join the infrared discussion list. For any information, support, or troubleshooting not covered here, please look to this epic thread about the Mobius Action Cam at RCGroups.com which contains a great deal of information about using and modifying the camera. An official manual for the Mobius Action Cam can also be found here: https://www.mobius-actioncam.com/downloads-info// Using the cameraThere are three basic modes to the camera, which you can switch through with the M button, and each shows a different color on the main LED.
(Artwork based on: http://publiclab.org/notes/mathew/05-10-2014/illustrating-infragram-point-shoot-instructions) Once you've loaded the custom white balance in the config file (see below) and charged up the camera, you're ready to use it -- just turn it on, press M twice, until you see a RED light. Then you can use the "Shutter" button which looks like: , to take photos. The red light will blink. Images should look roughly like the "GOOD" example below -- vegetation should appear generally pastel blue. An incorrectly white-balanced image such as the "BAD" example below may appear with an overall reddish tint. This means the camera probably has not accepted your config file, possibly due to misformatting or incorrect uploading.
Installing config fileIf your camera did not ship with a config file or you are using a new SD card, follow these steps to get your Infragram Point & Shoot to take properly white-balanced images, necessary for post processing at Infragram.org. This is also relevant for anyone who has a Mobius Action Cam and wants to script or customize its settings. The config file may also be used to set up Timelapse Mode -- see below at the Timelapse section. Note: The WB setting in the config file should be "7" but occasionally we've found that some cameras require an "8" -- if you have trouble, please post to the plots-infrared list.
TimelapseTo set the camera to Timelapse mode, you'll need to follow the above instructions for uploading a custom config file; you can use this one to have a 2-second timelapse, or tweak the To start timelapse mode:

An up-to-date version of this documentation will always be available on this page The Infragram Point & Shoot is a handheld, battery powered mini camera (a modified Mobius Action Cam) for doing plant analysis. It has been modified at the factory to replace its infrared-blocking filter with a red filter, effectively exchanging its blue light channel for infrared light. This is based on a great deal of research by Public Lab contributors and was initially pioneered in our community by @nedhorning and @cfastie. See especially these two research notes. Vineyards, large farms, and NASA all use near-infrared photography for assessing plant health, usually by mounting expensive sensors on airplanes and satellites. At Public Lab, we've developed a Do-It-Yourself way to take these kinds of photos, enabling us to monitor our environment through quantifiable data.
Our technique uses a modified digital camera to capture near-infrared and red light in the same image, but in different color channels. We then post-process the image to attempt to infer how much plants are photosynthesizing. This allows us to better understand and quantify how much of the available light plants are using to produce sugar via photosynthesis.
