Ahhhh--- I see, er, I focus

a bit of what you're saying. When I want to take a photo I do have to press the big, shiny, blank, button just HALF the way down .... until a GREEN square appears around the main part of what I'm looking at.
Then I press it all the way down.
I don't even know where the manual IS. My husband, bless his heart, hides manuals. He knows if I try to read them I'll get too confused, lose my temper and ........... well .....................
He understands things like manuals but he won't/can't even paint the living room walls
