“A picture is worth a 1000 words!”
An Infrared Image interpreted correctly
We have all heard this phrase; however, when looking at an infrared image, we should add, “if interpreted 
correctly!”
Many infrared imagers are advertised as fully automatic instruments that require nothing more than “point and shoot” operation. While thermography is a science, it is also an art or craft requiring a skilled human operator for both conducting the inspection and interpreting the data obtained. Accurate analysis of thermal imagery still relies upon a properly trained and experienced operator who thoroughly understands the structures or systems that he or she is inspecting.
