Tips for taking clearer photos
Holding the camera correctly
Make sure not to block the screen, lens, flash, or microphone.
Make sure not to expose the lens to direct sunlight. This may discolour the image 
sensor, or cause it to malfunction.
Half-pressing the Shutter button
Press the Shutter button halfway down to adjust the focus. The camera adjusts the focus, 
exposure, and white balance automatically, and the focus frame turns green. The focus frame 
turns red if not focused.
