I generally end up taking multiple shots of a location – since it’s difficult to make out which shot will work out better. Here are a few samples –
These pictures are of the water body in our society. The vertical shot lays emphasis on the water body where as the horizontal shot focuses on the location and shape – between two curved roads.

The vertical picture emphasizes the pine needle clusters against the backdrop of the sky and the horizontal emphasizes the greenery contributed by the tree. Personally I like the vertical one since I was trying to capture the pine-needle-cluster effect.
