I had seen this unique, natural image of a heart online, but finding it was a bit of a challenge. Eventually, I found it along a nature trail on the southern coast of Portugal. The immediate foreground in combination with the double arched rock formation formed the heart, and only a wide angle lens (16mm in this case) could capture this image. I used an aperture of f/16 so the depth of field was sufficient to include both the immediate foreground and the background. With this particular focal length, I focused to about 5 feet. My formula for maximizing DOF -- in other words, using the concept of hyperfocal distance -- is to divide the focal length of the lens by 3, and in feet that's the distance where the lens should be focused to capture the greatest amount of depth of field given the lens, the lens-subject distance, and the aperture. 16mm divided by 3 is a little more than 5. My other settings were 1/125 and 2500 ISO. I was very uncomfortable being so close to the edge of the cliff, but I really wanted the picture.
