1. Get Basic Composition
 
The heart of a photograph is its composition—the position of different elements in a frame. The easiest rule of thumb to learn and remember is the Rule of Thirds. Basically, you'll want to break your frame into nine squares of roughly equal size. Try and align the subject of your photo along these lines and intersections and imagine the main image divided over these nine boxes. This gives you a more dramatic, visually interesting shot than one where you subject is located dead center. Many newer cameras have a rule of thirds grid overlay that you can activate when shooting.
 
 
2. Adjust Exposure Compensation
 
As long as you aren't shooting in full manual mode, your digital camera is making decisions that determine the exposure of a photo. this means how light or dark the shot appears. Generally, a camera looks at a scene and tries to determine the appropriate exposure based on the correct lighting, which is why there are special scene modes for snow—without them, the camera would try to make the white snow gray.
If a photo is too light or dark you can either delve through the dozens of scene modes that are available in modern point-and-shoot cameras, or simply set the etting to automatic and the exposure will be done automatically by the camera.
 
3. Get the right angle 
 
Too many photos are taken from our eye-level because it's the most natural way for us to take them; but bringing the camera down to the eye-level of the subject will create a much more natural-looking image. 
A relatively simple image can also be made to look more dramatic by changing the camera angle, by tilting it to one side, or by changing your own perspective. Try taking a picture standing up, then crouch down or lie down. this will make the image look more imaginative.
 
 
4. Using a flash
 
Most people leave their camera's flash on automatic, which means it only gets used at night and indoors. However, by changing the settings you can take more creative pictures. One of the biggest problems with taking pictures outside is that parts of the face can cast shadows. 
To even this up you can use a technique called fill-in flash, by setting the flash to go off even though the camera thinks there is plenty of light. The flash will eliminate the shadows and give a better tonal range to your subject. 
At night, you can take some great shots by turning the flash off, but you will need to make sure the camera doesn't move, as the exposure time will often be longer and then the image will be out of focus.
