“Since I wanted to image wide-angle landscapes in high resolution, and my thermal camera’s field of view was only about 24 degrees, I had to put together a DIY rig to panoramically scan the scene.”

The pictures show the heat that makes Iceland what it is. One engineer with a weekend hobby did what the camera makers never bothered to.
