Notes on post-processing
My post-processing workflow usually involves some or all of the following:
Stacking multiple images in DeepSky Stacker (freeware, mostly for deep sky images)
Removing light pollution gradients using Iris software (freeware)
Stretching the image histogram using small repetitive levels adjustments in Photoshop Elements 2020
In PSE 2020 levels, using the black pipette to set the background sky black level. This level has to be set at a value of about 25, 25, 25, not the default 0,0,0.
In PSE 2020 levels, using the gray pipette to adjust the background sky color balance.
Using Topaz Adjust and Clarity plugins to increase contrast and color saturation.
More advance techniques can be found in the References section.
