> Even in highly-contrasted images, it appears as though every value between 0 and the highest value is used. That means if the high point in a given image has value 254, every value from 0 to 254 appears somewhere in that data. For a second, I thought this was talking about histogram equalization. [1] But I see what he means now, it's weird that there are no discontinuities. But wouldn't a discontinuity happen in a _low_ contrast image? If the thermal sensor only picked up 2 raw values, right next to each other, it would have to assign one to 0 and one to 254, leaving the rest unused. That is, color banding.
