What is Infragram?
An "infrablue" image is one in which the "red" channel of the image shows "near-infrared" light instead of the usual red. Such images can be generated using many inexpensive digital cameras and webcams by removing the infrared block filter and then adding a filter that selectively blocks red light (this is something the Public Lab Infragram kits nicely accomplish).
