My Nikon d3100 allows me to take pictures out of focus in Live view

When ever am shooting in auto focus in live view. My Camera allows me to take the pictures out of focus! Pictures tend to come out blurry help.

Yes, you have to learn how to correctly use the Auto Focus.

Place a pre-set focus area on your subject, press the shutter button down half way, and it will focus correctly. If you are in low light, your camera might have a hard time with AF, so you might have to switch to Manual Focus and do it yourself.

If it is allowing you to do it that means that you are doing it so just stop putting it out of focus…

RTFM. Then, your problems will be no more. If you don't recognize the acronym, google it. I don't know why the concept is so foreign to as many people as it is, it's pretty much common sense. It should be the very first thing you do before your hands touch the camera.

Then i suggest taking it out of live view or using manual focus.

Also, read your manual.
