General description of the script

This Sentinel-2 aesthetic script can be used to produce beautiful, neon looking results over urban and dry areas. The script is especially useful to highlight value differences in deserts. It’s essentially an RGB composite, with a B12 and B04 difference (which does a good job at displaying certain desert features, like dunes) in the red, B03 in the green, and B02 in the blue channel. Gain and gamma in the script can be modified to fit the location best; for gamma, -0.55 to -0.95 is recommended, while for gain, 2.3 fits most locations.

Compare the amount of information the script provides in dry areas compared to the true color composite.
