Figure 3.

Left-hand side shows a ‘naked eye’ image of an active wildfire; right-hand side shows a simultaneously acquired NVG image of the same fire from the same viewpoint. Note that, since the eye has a very large dynamic range compared to the camera, the outlines of the forest canopy, the shoreline and so on were more visible than in the camera images presented. Even so, little or no evidence of the fire could be seen by the naked eye. Reproduced from [56] with permission.
