Long shadows cast by a subject can become an important part of a picture’s composition by concealing unwanted clutter in a photo. Such photos also create some contrast for the colours or brightness of the subject to stand out.
The photographs with long shadows are generally captured from the ground level. When shooting from ground level at such times the light can be wonderful to get a part of the shadow in frame. While shooting down captures the way light hits objects in ways that can give a whole new perspective on a subject.
One must try both aspects, shooting from ground level as well as shooting from a high position. The height and angle of camera can produce a wide variety of subject appearances along with its shadow.
