How can I retouch photos of supernova veils to remove the smallest stars of the picture?
The goal is to allow the viewer to focus on the central nebula remains pattern, without too many stars artifacts.
Two examples are:
My first idea was to use Adobe Photoshop for
Blending Options > Blend if... and adjust levels, but if I raise the lower luminosity threshold to discard of less luminous pixels, I discard too the aura of the luminous items.
I had no more chance with curves, but I have no real intuition or knowledge about how to efficiently use curves to achieve this result.
This question isn't limited to a particular software, if a software is more efficient for this task than Adobe Photoshop, the answer seems interesting too.
