EXAMPLE ONE :
I took this first photo on a recent trip to Manchester, it was a dark
wet miserable day and the result of pointing the camera up towards
a bright gap in the clouds, created a flat shot of the ride, when you
roll your cursor over the picture you will see how returning later
when dusk had rolled in with blacker clouds, how the captured image
has come to life, the weather was still the same!

EQUIPMENT USED :
Digital Camera Body /auto exposure (1/15th) /F 6.5 24-85 zoom lens

MY TIP :
Consider were the sun or light will be later in the day, what will your
subject look like with the light from a different direction, would it
look better? If so, try and get back to the location later at that time
It will all help you to learn to see :-)
