A reddit user (djrbx) posted a quick gallery comparison of the Lumia 1020 and 920’s cameras. The 920’s camera has never been a slouch but compared to the 1020 it looks like any other phone. It’s interesting to see the white balance in default mode has been fixed (all previous Lumia’s had some serious white balance issues); but it seems that there might have been some overcorrection, where it carries a slightly yellow tint (or perhaps it’s all relative?).
Of course the white balance can be fully controlled through the Nokia Pro cam app (so perhaps the white balance on the 920 will also be fixed once we get it).
