A question I have relates to the "best"
luminescence of the background sky. In order to bring out faint nebulosity, the
overall brightness of the image is enhanced, which means the background sky
becomes paler as well. I was wondering whether there was any standard used
by members that defines how dark they would like the sky as a function of not
compromising the fainter portions of nebulae and the fringes of galaxies, etc.
Thanks,
-Charles
(PS.regarding my previous posting on Noise and
Blur: Robert, I did figure out the color range selection tool in PS, and I am
using it now along with smart blur. I now have a good method of dealing with
grain, using another software as well. Thanks everybody for your suggestions.
They were very much appreciated!)
