The next time you go out on your apparatus to the grocery store or just sitting around the fire station take out your TIC and start learning to read the contrast in the pictures. Take one hot and one cold item and sit them in a room of a different ambient temperature. While at the grocery store scan the store learn to make out shapes and sizes as oppose to temperatures.† You will be amazed at how much better you become reading the picture on your TIC. This drill was inspired by the instructors from Safe-IR who conducted a Thermal Imaging Class for my department last year. Thanks to Bob Knabbe, and Tom Decker.
