Although today's digital cameras are easy to operate, taking quality pictures takes a little practice.
You don't need to spend a lot of money on a camera and you don't need to be a professional photographer.
Knowing the basics of good picture taking will result in you being satisfied with the results you get from any camera you own.
First, you will want to read the manual that came with the camera.
Knowing how to use the flash, zoom or other features will make it easier to get a good quality picture.
Take some test shots and check the results.
Using a digital camera is very easy as you can see your picture right away and don't have to wait for them to be developed.
Here are a few simple tips:

• Try taking pictures from different angles and use the portrait and landscape orientation.
  
• Mix up your photo taking by having your subject in the middle and then the sides of the frame to see what looks best.
  
• Remember to make sure the light is behind you and on your subject.
  If you are taking pictures outdoors, try to avoid direct sunlight and consider taking your pictures on overcast days.
  
• Test out the zoom on the camera to see what results you get.
  Take long distance photos also.
  
• Take pictures in shadow or reflections in water or glass.
  
• Don't be afraid to use the flash outdoors.
  
• Professionals use a tripod when taking pictures; you might want to try one too for a clearer picture.
  
• Take extra batteries for your camera.
  
• When taking close up shots, if you don't have an image stabilizer on your camera try using the tripod.
  
• Make your pictures personal by taking them in natural settings or having people involved in their normal activities.
  
• If you want people to look natural when they laugh tell them a story or joke rather than getting them to say "cheese".
  
• Some of your best pictures could come from catching people unaware.
  They will be more relaxed because they aren't aware that you are taking their photo.
  
• Consider the background in your picture.
  You don't want it to distract from the picture.
  
• To take action pictures with a digital camera remember to move in close and increase your camera's shutter speed.
  Also, anticipate the action and take multiple shots.
  If you are prepared you will be able to capture the players face when they make the winning goal!

Taking a good quality picture just takes some time and practice.
You can read books and check out websites but the best way to learn to take a quality picture is to experiment.
