The infrared imager makes images in several different pallets. In this image, the white areas are the hottest, black areas are coldest.
Same ducky, different pallet. Here black  areas are hottest.
This pallet is called rainbow. Note how it brings out the "reflection" of the ducky on the surface of the table.
This is Ozzy, a domestic long hair. Using the scale bar at right, we can see how the shorter hair on his face, ears and paws allow more of his body heat to escape. It also shows his nose is one of the coldest things in the image, while his eyes are the warmest.
These images show a failing transformer connection. Identifying problems such as this not only prevents catastophic failure, but also leads to lower energy costs.
