Hi Folks,
|gdal_translate| has the option |-exponent <exp_val>|
<https://gdal.org/programs/gdal_translate.html#cmdoption-gdal_translate-exponent>
to use in conjunction with |-scale| that will
/apply non-linear scaling with a power function. exp_val is the
exponent of the power function (must be positive)./
This describes what the function does at the mechanical level but not
why or when it might be a good idea. What are appropriate scenarios to
use this feature? How is it useful and what does it accomplish?
For example to perform https://en.wikipedia.org/wiki/Gamma_correction
