EXAMPLE ONE:
Before you actually take a picture, take a good look, what is
actually seen in the frame of your viewfinder, don't be over awed
by the view alone, the picture here, taken in the Swiss Alps, has
been cropped closely and is exagerated for this example, when you
roll your cursor over the picture you will see how a few steps to the
left avoids the pylons.

EQUIPMENT USED:
Digital Camera Body / auto exposure / 24-85 zoom lens.

MY TIP:
Practise mentally by just looking around and seeing what would be
in a picture if you took one, you will eventually learn to see :-)
