We have established that the use of line can effectively lead the viewer into a scene or, at the very least, extend an invitation to enter the scene. But line can also make it clearer what we wish our audience to look at; that is, what is of primary importance. In the first image, notice how the lines come to a screeching halt at the small pool of water, even though the lines were intended to lead you to the intended subject, Kathleen Clemons, photographer extraordinaire and the director of student happiness at my online school, PPSOP.com. In the second image, the lines do lead to Kathleen. Rather than stopping at the water’s edge, they seem to frame Kathleen, or at least her reflection.

Both images: Tripod, Nikon D3X with 16–35mm lens at 16mm, f/22 for 1/30 sec., ISO 100
