Upload an "infrablue" image for processing
An "infrablue" image is one in which the "red" channel of the (JPEG, PNG, GIF) image contains primarily "near-infrared" information. Such images can be generated using many inexpensive digital cameras and webcams by removing the infrared block filter and by then adding a filter that selectively blocks red light (this is something the Public Lab Infragram platform nicely accomplishes). For more info, check out Public Lab's guide to near-infrared imaging.
If you don't have your own "infrablue" image, you can try this example infrablue images below. Click on the image to see what it looks like after being processed:

How it works
Use the even more experimental Infragram Sandbox tool to try out different indices and compositing techniques with your Infrablue images.
