In order to adjust your picture to exposure duration go to the which tab

Explanation:
Underexposure happens when the film or camera sensor is not exposed to enough light. As a result, the photograph loses shadow detail and the dark parts are almost all black.
To determine if you have proper exposure on your digital images check your histogram on the back of your camera after every photo you take. It sounds like a lot of work to do this, but trust me, if your exposure is correct, you will have less “fixing” to do to your images afterward, so really, it's a time saver.
THERE ARE TWO DEVICES TO CONTROL EXPOSURE….
THE SHUTTER – is usually a curtain-like device just in front of the sensor. Think of a shade pulled down on a window, and then quickly open it and close it. ...
THE APERTURE – which is built inside each lens and controls how much light enters the lens.
Keep adjusting the exposure compensation until you get it right. When you're done, be sure to set the exposure compensation back to zero! For manual exposures, start by changing the aperture and shutter speed until the meter indicates that you have the correct exposure then adjust from there
