Camera shake ( Holding the Camera )
Because digital camera owners are not paying for film, they tend to "snap" everything that moves while looking at the LCD rather than the viewfinder. This may cause you to hold the camera unsteadily and leads to camera shake and blurry pictures.
If you use the optical viewfinder, you can support the camera with your hands and your face.
But with the LCD you only hold it with your hands.
To prevent camera shake, hold the digital camera tight using both hands and keep your elbows poised against your body when taking a picture.
It is also a good idea to lean against something for support.
