Wow the pictures that I see you guys have been taking is seriously great. I am not getting this nice pics at all and feel that the camera is not worth it. I take better pictures with my Note 2, not sure if its me or the phone which is a problem. I have observed lot of grains in the pictures.
Here are a couple of photos I took with my Lumia 820 using ProShot (that app is absolutely UH-MAZING!)
First image: Considering that this was taken through a window of a fast-moving train, I thought this came out quite well with lots of detail.
The whites are a bit washed out here, but it was really sunny and I haven't exactly got the hang of all the ProShot settings yet. But I LOVE the colours in the sky.
