Web2 Answers. An HDR image has a high dynamic range, which means a very large ratio between the brightest and darkest parts of the image. An HDR image on a normal (low dynamic range) monitor will actually look very flat: This is because that huge range of brightnesses has to be compressed to fit into a much smaller range of brightnesses. WebThe Tonemap flag, when switched on, activates the Exposure and Contrast parameters. The other types of Tone Mapping (other than Simple) do not have this flag.
