Press halfway
This refers to pressing the shutter release button gently to the first
position. This locks the focus setting and the exposure. The green focus
frame lights on the display when the shutter release button is pressed
halfway and the subject is in focus. If the subject is out of focus, the
frame turns white.
Press fully

fully depressed position. This takes a picture.
