I've been having some problems w/ my camera (Sony A7RII) lately - specifically night photography, sometimes long exposures, but not necessarily. Overall, shooting RAW, I get poor quality images and banding in the sky, or posterization, especially anywhere there is smoke or fog, clouds, etc. I could swear this wasn't a problem when the camera was new. I reset all my camera settings but still. Generally, lately, the night images tend to look muddy, especially in the conditions above, or when shooting in a club w/ colored lights, especially red lights. Before sending it in for repair, I tried to do some experimenting and noticed that some of the problems with banding/posterization were only in Lightroom. As far as the muddiness and colored lights and some banding/posterization, that seems to be the camera itself. But for the images giving problems in LR, when I open the same file in Photoshop, the sky is actually clear. Also If I crop into the image in LR sometimes the banding is reduced (like maybe it's processing that area better), but it never looks great. When I export the file as a jpg, some of the banding is also better. But it seems overall that LR is not handling the files all that well. Any thoughts?
