I've only had my EOS 70D for two days, but I have taken a 5 hour online crash course on the camera. As of today, I can't get completely out of live mode when taking pictures. I can see out of my viewfinder, but for some reason, the live view area never goes away and stays on screen. Yesterday, it worked correctly, but no matter how many times I press the Start/Stop button now, the live view mode stays up on the screen. Help!
