Does anyone have any suggested settings to take optimal pictures? I don't expect dslr quality here, but if ever there's movement (which is almost always) there is blur in the pictures I take. Flash is on auto, have anti-shake option ticked. Only a couple in 100 photos so far are crisp throughout the entire depth of field. I have an otterbox commuter case that covers the light/proximity sensor but wasn't sure if that has anything to do with the auto-focus of the camera? Thanks.
