Isolate the Interesting Part The eye tends to see the whole rather than the individual parts. It also sees whatís near and not whatís far. By bringing attention to those things missed by the eye, you can create many interesting pictures. It could be the grimace of an athlete, the grill of a classic car, or a girl against a blurred background. Telephoto lenses can also compress images to give dramatic effects. You are limited only by your imagination.
