Hello. My name is Pavle. I'm a young photographer. I have just started, so I'm a beginner so I'm still learning. Focus (that square thing) was set on this guy's body (stomach) and not face. What I'm trying to ask is if that (square) is on his stomach will only part of that body (stomach) be in focus or his whole body including his face? Will his face look clear and sharp or no? On some other pictures that I took of him, that same square was on his face, but his face wasn't even clear/sharp, it was blurry?! I am so confused. Can somebody please help me? I'm trying to compete in a competition, but I don't even know If any of this pics are good?! Also, sorry, English is not my first language. Thanks a lot.
