Sounds pretty elementary but holding your camera correctly can help you get better photos.
You might not know it, but there is a right way and a wrong way to hold a DSLR camera. The correct way is to support the lens by cupping your hand underneath it. This is usually done with the left hand, with your right hand gripping the body of the camera. This helps to prevent camera shake. If you are gripping your camera with your hands on either side of the camera body, there is nothing supporting the lens, and you might end up with blurry photos. To get an even stabler stance, tuck your elbows into the side of your body.
It you have a small point and shoot or are using your phone the trick is to be very still. Try holding your breath when you touch the trigger. Always take more then one.
