Nokia's new camera app already available in Windows Phone Store
Nokia Camera allows you to make the changes you want so you can take great photographs. With auto mode, those using the app will be able to quickly change settings if they are taking an action shot, or using the camera at night. Manual mode lets you control settings like white balance, ISO, focus and shutter speed. This will let the more experienced photographer set up a picture the way he or she wants it. Smart mode will allow you to combine shots taken of a sequence to focus on motion, remove motion or change faces so that everyone looks their best.
The app allows you to store the unedited, original versions of your photos so that you can zoom, reframe, and edit them well after they have been snapped.
