Learn about your "+ & -" setting on your camera
The light meter on your camera has a system you should know about as your "auto" setting may just not work in certain situations. Essentially, it averages the highlights (sky) and shadows (dark parts).  Then it sets your camera's shutter (how quickly the picture is taken) and iris (the size of the opening of the eye of the camera) so the resulting image will be light balanced (in black and white photography, a light grey colour).
An example of this is wedding pictures - if you are shooting folks in back suits, the camera will attempt to "average" the luminosity and the blacks come out grey ... as do the whites. (You may not notice this as your photo lab may make the corrections for you).
Another example of auto not working is with this image - a bright sky near the centre of the image. Again, the tendency for the "auto" setting on your camera is balance the light and probably result in an under exposed image.
So, what is the solution? Learn about your camera's settings. One real neat one is your "+ & -" adjustment. Essentially, if you take an "auto" exposed picture and it is too dark, hold down your "+ & -" button and set it to +1 or 2 and take another picture. What is happening here is you have told your camera to "over expose" the picture by adding more light. Alternatively, if it is over exposed (too bright) do the reverse and select -1 or -2.

Here is the technical information about this image.
An incoming storm at Princess Margaret Marine Park (Portland Island BC) attempts to smother the evening light and almost succeeds. Thirty minutes later the clouds did smother the sun only to offer lighting in exchange.
