We would like to serve data as they are, without uncontrolled changes, because it is almost impossible to set color balance to one fitting all places in the world and all groups of users. You can still tweak contrast in several ways.
Figure 1: Raw picture.
You can tweak "Gain" (brightness) to automatically equalize the image.
Figure 2: Gain adjusted to desired values.
You can tweak "Gamma" (contrast) as well.
Figure 3: Gamma adjusted to desired values.
Configure atmospheric correction setting either to DOS-1 or to “Full”.
