Thanks Glenn. ArcsinhStretch is extremely powerful and can easily ruin
things. I’m no expert either. However there’s a few things I have
First of all, use ArchsinhStretch mostly just on RGB data. What I have
typically done is used ArcS on just the RGB image and use other stretching
methods for the LUM. For this image I did use ArcS on the LUM data, but
very sparingly. Since the RGB data can be heavily smoothed, the little
black dots and other artifacts I see with ArcS can be smoothed out.
After clicking on “estimate black point”, and showing the clipped pixels, I
always need to move the slider to the left until there are just a few
clipped pixels showing.
Run ArcS in two or three passes instead of all at once.
