Hello,
I have a problem with some very indistinct blotchy discoloration in a clear sunset sky which has resisted my attempts at correction. The image is a 100 MB file so everything including these blotches, is very large in pixel terms. Using various blur techniques has not yielded good results primarily because of the large pixel dimensions of the blotches. I end up with waves of discoloration instead of blotches of discoloration. I can easily isolate the sky, and the best I've come up with is to resample down drastically, add Gaussian Blur, then resize back up with stair interpolation. But this yields some grid pixelization in the sky. Perhaps there's a better way? Here's a link to a small crop of the image: http://www.pbase.com/image/10142424/original
Scrolling the image or emphasizing with Levels will more clearly show the discoloration.
All suggestions are greatly appreciated.
