I'm not that well versed in how cameras work and I've been trying to read up on the subject but I'm a little confused about something. I understand that both the iPhone 4S and 5 take pictures in a 4:3 aspect ratio so when holding both phones in landscape mode a picture will appear shorter on the 5 due to the 16:9 aspect ratio of the screen. However, when holding the phone in portrait mode, why does the 5 take a picture that is shorter in length than the 4S? I've taken multiple photos with both phones of the same image and every single time it comes out shorter on the 5. Can anyone explain this to me?
