Instructions
Install freshly charged or new batteries and an empty memory card into your camera, turn the camera on and set the camera to "P" for Program. If your camera does not have a program button, try the function or settings button, or check the manual to find where to adjust the exposure.
Adjust the camera's flash output to match your setting. In a dark setting, the camera will want to illuminate the scene so it looks like a daylight shot. In some cases, you might want the scene to be a little darker to catch the mood or ambiance of the picture. Look for a button with a "+/-" symbol on it. The is called a compensation button, and it can be used to adjust the exposure or the flash.
Press the "+/-" and use the control dial to move the cursor till it reads "-1" this will underexpose the picture by one "stop," which is a measure of exposure.
Turn on "Red Eye" removal. Some newer cameras have a red-eye removal feature included. When this is active, the flash will fire a couple of quick bursts of light at a lesser setting so the subjects' pupils will close slightly, thus reducing the amount of red-eye in the picture.
Hold the camera to your eye and frame the picture the way you want to shoot it, press the shutter release button to take the picture.
