BASICS
Tricks are of little value if you don't have the basics down.
If you don't know how to use your camera, you can't apply some of the tricks.
The photo books and your camera manual will take you through the basics.
Let me give you a couple real examples of basic problems.
My sister-in-law asked me why her pictures were blurry.
When I watched her, she was holding the camera out at arms length from her.
So there the camera was, shaking up and down in her out-stretched arms.
She was NOT going to get a sharp picture with the camera moving and shaking like that.
If she were shooting video, I would get sea sick watching the video.
So first order of business, was to learn to hold the camera so that it would not be shaking up and down.
How do you press the shutter?
I've seen people using their ARM to press down on the shutter, not their finger.
The right side of the camera visibly moves down when they push down on the shutter.
They are not pressing the shutter, they are actually shoving the right side of the camera down.
They need to learn how to properly press the shutter, without moving the camera.
