BandMath application is intended to apply mathematical operations on pixels (launch it with shortcut CTRL+A). In this example, we are going to use this application to change the dynamics of an image, and check the result by looking at histogram tab, in the right side dock. The formula used is the following : im1b1 ×1000. In the figures below ( 2.7), one can notice that the mode of the distribution is located at position 356.0935, whereas in the transformed image, the mode is located at position 354737.1454, that’s to say 1000 times farther away approximately (the cursors aren’t placed exactly at the same position in the screenshots).
