Can either of you post a screenshot? It would also help if you gave the location, time of day and altitude you took it at. It could be similar to an issue I had been having but had fixed on my setup where there was a giant square of sky directly above that was either darker or lighter than the rest of the sky, and only appeared during dawn or dusk conditions. I have no idea what causes it or why it eventually went away.
