Here is a set of comparison photos of the same macro subject taken at different f-stops. Each of these photos have photographic and artistic merit. It is a matter of personal opinion as to which image is best.
The cucumber vine and leaf were about 10 inches from the camera. The background leaves were 1 to 1.5 feet behind the subject.
All of the photos were taken at the same time using a Canon 100mm f/2.8 macro lens on a Canon 30D camera, using a tripod and remote.
