I'm shooting with the LCD turned in so it's not visible at all when I'm taking pictures. Before I pack up, I'll review them on the LCD and retake any that I don't like. I'll delete the really bad ones there, then head home and see if any of the rest are salvageable.
I'm always astonished what the camera actually captures as opposed to what I could see on the LCD. If I do my job in composition, then the camera and PhotoShop will let me end up with good images.
