Tone mapping: contrast & dynamic range
As a next step create a tone-mapping (S-curve) to improve the mid-tones of the
image. Select the magnitude of the s-curve from 1 to 5 (or your custom setting):
range containing no information. This will shift the left side of the histogram
closer to the vertical axis of the graph.
This method helps to remove a significant part of the noise without losing
dynamic range (as no information is clipped), and without losing sharpness
(as no median filter is used)

Apply some histogram stretching by entering new
minimum and maximum DN values
(for example: 5 / 220). Do not use excessive
histogram stretching as this may lead to additional
noise (maximum 20%).
The image with the adjusted histogram is shown in
the image preview.
