One of the most powerful tools we have as photographers is the ability to manipulate the viewer’s sense of scale. Why does this matter?
When the viewer first looks at an image they look to think they have have correctly assessed the contents. If, in fact, they realize they have not, or they sense ambiguity in the subject—as in, “What exactly am I looking at?”—the result is a double-take.
This double-take leads directly to a clean slate. By misdirecting the viewer, we have given them the chance to view some portion of the world with new eyes. This means showing people something in a way they haven’t seen before—which is the goal of much photography.
Case in point: I shot the image above on a rock at low tide in the intertidal zone at Drakes Beach in Point Reyes National Seashore, CA. For all the world it looks like a vast landscape from above, but as soon as the caption is noted the viewer will automatically adjust scale and visual expectations.
