Most of the power used by a digital camera is used to run the LCD display on the back of the camera. If you can, avoid or limit use of the LCD display. The batteries will last a lot longer. Using a memory card reader will also help to save your batteries, especially if you use a slow connection like RS232 serial. Some brands of batteries do not work well in the high-drain conditions of a digital camera and will seem to be dead after a short period of use (ironically they can then be used to power children's toys or other devices for a long time!)

Use batteries that are designed for use in high-drain devices or special 'photo batteries? Battery manufactures are aware of these problems and change their designs for these applications. Some cameras can use rechargeable batteries and although expensive can save a lot of money in the long run if you take a lot of pictures. Low temperatures affect the performance of some batteries. If you plan to take pictures in sub-zero conditions, try to keep the camera (and hence the batteries) warm; perhaps by keeping it in your pocket.

Many digital cameras contain a range of features to help take great pictures. This is especially important when taking pictures in poor lighting conditions or taking pictures of fast moving objects. Read the instructions that came with your camera and experiment to find out how to take the best pictures. There are many differences between film and digital cameras and even if you are used to using a film camera you may find it useful to learn about these differences.

When using a digital camera make sure you have enough batteries. Digital cameras use a lot of power, especially if you use the display a lot. Make sure you take spare batteries and recharge rechargeable batteries before going out. Also make sure you have enough memory cards to store your photos. If you use a card reader to read the files into your computer, check that you have put the card back in the camera before you got to take more pictures!

Good photographs are good for both technical and aesthetic reasons. While the aesthetic issues are a matter of personal taste, many otherwise great photos are spoiled by poor technique. Here are some things to keep in mind when taking pictures:

1. Get Closer. Most amateurs frame too far away from their subjects. Look through the viewfinder! This is especially important when photographing people. Professionals typically use long lenses (85-105mm) for portraits. Most point and shoot cameras on the other had have 35mm lenses.
2. Include people in your shots. The addition of people to pictures adds atmosphere and context. It makes the subject easier to relate to and sometimes gives a sense of scale for small or large objects.
3. Capture Action. Keep the people moving and try to 'catch the moment?/li>
4. Simplify the Composition. Simple compositions are easier to understand. Uncluttered backgrounds offer less to distraction the viewer and allow them to focus on the subject material
5. Put the Subject Off-Center. Try to place the main subject off the center of the picture. Professionals use a 'rule-of-thirds?and place the main subject one third of he way across the frame. Why this works is not well understood, but it can be very effective.
6. Vary the Angle. Varying the angle can add humor and drama. Almost all photos are taken from eye-level, but there are many other possibilities.
7. Put Foreground in Scenes. Foreground detail gives depth to the shot and adds interest and context. It can also be used to frame the subject.
8. Pay attention to Lighting. Where is the sun? Direct sun can give too much contrast but not enough light will lead to poor images and possibly camera shake. Light alone can 'make the shot?
9. Use the Flash. Flashes can be used to improve the lighting, even outdoors on dull days. But be aware the effective range is very limited. Adding additional natural light to a room will also make the effect look more natural.
10. Hold Still. Camera movement spoils many otherwise great shots and is often mistaken for focus problems. Hold the camera steady - brace against objects. The flash can help to freeze the action.
