Subject: Re: Improving an image

I posted a fourth image with the Image Controls.  Turning off Noise Reduction made it sharper, and turning off Saturation a little smoother.  Then I brightened it up with curves.  Now you can see festoons and the great red spot pretty clearly.

Hi Howard;

Thanks for the details.

It's the use of  the "Median High" for Noise Reduction  and leaving the Saturation at 0.90 that give it that "chunky" look in image processing

I would also reduce the "Rad 1.0"and "Rad 1.5" sliders as they tend to amplifies pixel noise.

HTH..

I redid the stack after some suggestions from Milton and rereading the appropriate sections of the manual and posted the log file for the first two images.  The third is the same as the second stack with different Image Control settings, which is on the post.
