Many natural wonders are so vast they are hard to express. I personally find the Grand Canyon overwhelming beyond belief! But other natural structures are vast as well. If you just photograph a waterfall or rock formation it may be technically great, compositionally pleasing, but the grand feel you felt from it is lost. What to do?
Add a sense of scale. Use a person in the image to scale the subject. Both of these images give a sense of the scale of the feature. The person on the bridge behind the rainbow is tiny! (My friend and fellow photographer Rod Barbee, check out his site: www.barbeephoto.com). The person gives a sense of scale to the vast old growth forest and the waterfall in front of him.
The second image to a lesser degree also conveys a sense of scale. I posed my student Sam in this narrow area to show the size of where we were walking. I like the fact you can’t see the top or bottom. It leaves the scale to the imagination.
So next time you are overwhelmed by the sheer vastness of nature, add some scale!
