A common problem that our mini-class attendees have when using their cameras is ‘camera shake’. That's when images come out out of focus or blurry – usually because the camera wasn't held still enough when the shutter is pressed.
It's most prominent when shots are taken in low light situations & the shutter is open for lower shutter speeds.
Even the smallest movement of the camera can cause that and the only sure way to eliminate it is with a tripod.
Wait, you say...Isn't that what image stabilization's for? Well, the built-in stabilization programs in current cameras do help in steadying the camera with a minor handshake that occurs when you hold a camera for an extended amount of time or in lower light BUT will not help much you move the camera while activating the shutter in an out of the ordinary action.
Adding to what's mentioned above is the way current DSLR camera owners hold the camera (especially in live view mode...); at arm's length away from them as they take pictures – with just one hand. While this might be a good way to frame your shot, the further away from your body you hold the camera, the greater chance you have of swaying or shaking as you take your shot, resulting in that blurry shot! So, to make sure that your shots can be the best they can be, this is how you should hold your camera... 
- Use your right hand to grip the right-hand end of the camera. Your forefinger should sit lightly above the shutter release, with your other three fingers curling around the front of the camera. Your right thumb should grip onto the back of the camera. Most cameras these days have some sort of grip to help you hold it steady. Use a strong grip with the right hand but don’t hold it so tightly that you end up shaking the camera.
- Your left hand should support the weight of the camera and should either sit underneath the camera & under or around your lens if you have a DSLR.
- Use both hands if you're using a DSLR with Live View. Hold the camera comfortably away from your face to clearly see your subject(s) and maneuver your surroundings. Tuck your elbows into your body for added stability. This will also work for point & shoot owners as well.
- Additional stability can be found by leaning against a solid object like a tree or wall or by sitting/kneeling down. If you have to stand and don’t have anything to lean on for extra support, spread your feet to about the width of your shoulders to give yourself a steady stance. In other words, use two hands, folks!
