The resolution is quite low. Increasing it may help. Are you giving the camera the time to focus? Change the focus mode to single.Half press the shutter atleast twice and here the beep after focus each time. I have nothing to say about pic #3,4 . They are quite underexposed..... and naturally grainy. But #1,2 are embeded with some setting/operation problem.... set ISO to 50 or 100. Surprised to look at the red eye in #4....it never happened with me to such an extent.
