FIGURE 5. TMP 1981.006.0001, Tyrannosaurus rex, "Black Beauty". Increasing brightness in an LDR image and a HDR image.
5.1 specimen as photographed in the exhibit space at -3EV, 5.2 simulated HDR exposure. Histograms show total number of pixels at a given light level in the image. Both images processed to increase brightness of the image to roughly equal levels in
5.3 (LDR) and 5.4 (HDR). Note the lack of detail present in the histogram in 5.3, where the increase in brightness only moves the values present in the darker image, without making additional detail visible. Added information present in the HDR image allows values not differentiable at low levels to show additional information when brightened.
