This is a thermal infrared image of the creator of The Cosmic Mirror, yours truly, Daniel Fischer. It was taken in 1996 with state-of-the-art thermography equipment by Georg Dittié. The colors or grey levels, resp., represent surface temperatures.

At the bottom the temperature is displayed with a simple grey scale, black representing cold and white representing warm (not so say, hot) areas. At the top a look-up-table appropriately named HEAT is used, in which the color scale progresses from Black over Red and Yellow to White. This LUT is very popular in astronomy these days as it increases the number of 'colors' between black and white as compared to a simple grey scale, but still allows the direct recognition of what's dark and what's bright (the [in-]famous rainbow-like PSEUDOCOLOR LUT fails in the latter respect).

By the way: visible-light images of yours truly can be found in a conference report from Arizona, in this ESO photo from 1998, and in Sky & Telescope of Nov. 1997, p.81.
