My first From a Dummy tip is really simple,
In order to take good photos, you have to actually TAKE photos. Don't leave your camera at home in a drawer, take it with you.
Get in the habit of grabbing it if you're going outdoors, or if you're going shopping, you never know what you'll see and it's better to have it and not use it than to need it and not have it. My camera goes everywhere with me except to the bathroom and it's even been in there a few times when the kids were making mustaches and beards out of soap bubbles (couldn't pass that shot up!)
Aim your digital camera at your subject and press your capture button down just a little, this allows your camera to focus, looking at your LCD screen you will see your subject come in sharp and clear, if it doesn't, don't push the capture button all the way down cause you'll end up with a blurred photo. But if it looks sharp enough, click all the way.
And keep practicing, it might take a few snaps before you get the hang of how much pressure you can put on the button to focus without it taking the picture until you're ready.
