O HOW TO HOLD PETRI COMPUTOR tr
The format of your picture is deter,mined by the position in
which you hold the camera. Holding the camera in a horizontal
position will result in a horizontal format. Holding in a vertical
position will result in a vertical format. Blurring in a picture  is
often caused by camera shake at the moment of exposure.Practice holding the camera and releasing the shutter so you        rlII
can take pictures without jarring or shaking  it.
Use the following three simple rules for taking a picture to
avoid camera shake;

        1.    Before releasing the shutter, take a deep breath
        and hold it until the picture has been taken.
       2.    While taking the picture, hold the camera firmly
          with both hands and press the back against your
           face and forehead as firmly as possible.
       3.    Squeeze the shutter release button, do not prod or
          tap it. Practice squeezing until you can release the
            shutter without the slightest quiver.
