This is a nice cloudscape. Photographs from airplane windows often suffer the same problems this one does. The lens flare and the contrast probably contributed to the amount of post processing that was required to bring it back. The noise level in the sky is quite heavy. When I find myself in a situation like this, I usually end up trasing the photo.
This spectacular image, I'd guess, would score more than a half point higher in voting if touched up with NeatImage... You can see my temporary adjustment to it at.. //www.pbase.com/image/23025194
I will delete it after you have had a chance to see it. Great picture.
Wow, those are some beautiful clouds! I like the subject, very interesting and has great depth to it. At first I thought I could see some lens flare in the middle of the image, but upon further inspection, it appears to be your cameras reflection in the glass. Of course with the sun shining in, it's almost impossible to avoid reflections like this. You did very well with the resources you had at your disposal. Nice shot!
