Damn wrote heaps of good stuff and then lost it.
Well i thought it was good stuff.
Did you shoot in RAW or JPEG. If JPEG what size (L, M, S)
How did you download the image to the computer and what program did you open it with? Did you save changes when you closed it?
When you uploaded this sample was it a crop or full frame reduced? If a crop did you upsize it at all and if so what program did you use?
I know it's not possible but to me it looks like an out of focus dark frame.
