"But here's a first lesson....the shutter button to take the pictures....on almost all digital cameras, PRESS IT HALFWAY, AND HOLD IT THERE FOR A SECOND OR TWO TO LET THE CAMERA AUTOFOCUS BETTER, THEN PUSH IT DOWN THE REST OF THE WAY TO TAKE THE PICTURE. That will result in a crisp and sharp picture unless of course, you move the camera before or after it actually takes the picture."

Compliments of Will. Yes, please learn this skill when taking pictures. Blurry pictures suck.
