Hi Everyone:
I have an image processing question: I am getting
quite adept at pulling out faint nebulosity using the curves and levels tools in
Photoshop. The problem, of course, is that these faint wisps of nebulosity often
have a "grainy" appearance to them. Since I intend to print these images, and
not wanting to over-emphasize the grain, I am often caught in a quandary over
just how far to go when pulling out these faint details.
So I am using the Gaussian Blur tool to mask the
grain a bit. More specifically, I am using the Adaptive Filter function in Iris,
an image processing program. This tool has a similar effect, in that it blurs
the object and masks the grain. But now I am bothered by slightly blurry images.
So I have tried to use unsharp masking to compensate. But this solution is only
half-successful, because the image starts to get grainy again.
Does anyone have any solutions for this problem, or
should I just settle for the best balance between grain and blur? Thanks for
your insights,
-Charles
