My wife shot some videos of our daughter today and i noticed that videos look rather dark. I just tested my wife's iphone 5s (phone is one month old) and noticed that video mode is indeed dark, I did some comparison just to confirm my suspicion and in fact it turns out that videos are worse quality than videos that i shot with my iphone 5, on my iphone 5 videos are clearly brighter. I'm not sure if it's faulty iphone or is it 7.1.1 bug, can anyone confirm it? It appears auto exposure setting in video mode doesn't work properly. Strange thing is, in photo mode, iphone 5s appears fine. I don't remember having this issue until now. Btw, i'm talking about indoors videos, under nor very bright lighting or relatively low light.
