Sometimes it’s a little tough expressing relative size in a photograph. After all, it’s only a two dimensional representation of a three-dimensional subject. In landscape photography this can be especially difficult since the camera tends to “compress” the image perspective somewhat.
Take the shot above for example. Can you tell how large the waterfalls and surrounding rocks really are? Can you tell how close they are to you? Me neither! Which is why it’s always a good idea to add some visual clue to your landscape images to help viewers judge the size of your subject and distance the subject is from the viewer. In some cases a simple foreground object can be used to add this sense of “perspective”. In others it’s simply best to add people in your landscape images as shown below. There’s nothing better to add a sense of relative size than having a person in your shot.
(And yes, those folks were mighty close to the slippery edge out there. You should have seen me & my tripod :-))
