Lastly after finalizing your choice, check out how much of learning you will be required to do before you actually start using it. Digital cameras are quite different from the standard ones. Hence it may be worthwhile for you to sign up for digital camera tutorials- online or onsite to get yourself familiarized with stuff like how to initially set up a camera and how to click during different times of a day.
Picture Quality and Exposure The brightness, darkness or subtleness of an image taken from your digital camera will depend on “exposure” — which is the amount of light that hits the image-sensor array. The more light- greater will be the exposure and hence brighter would be the image. Restricted exposure which essentially means not sufficient light will make an image too dark.

In a typical DSLR Camera following exposure options will be there: Automatic setting: Most digital cameras have an automatic exposure setting which is a blessing to novices like me. Without too much doing on your part this setting automatically makes all the adjustments for you.
Priority: In certain models all that users have to set manually is either the shutter speed (the priority setting) or the aperture. The camera takes care of all the remaining exposure setting automatically.
Manual: In the manual DSLR cameras users can set both the aperture and shutter speed themselves.

Sensor-based exposure controls: There is yet another option available in some digital cameras which make use of chips in the image-sensor array. These chips in the image sensor array turn on and off for different periods of time, resulting in more or less light being captured.
Finally there are cameras in which the exposure is managed by increasing or decreasing the strength of the electrical charge that a chip emits in response to a specific amount of light.
