Anne has asked about focus. I'm going to expand the answer beyond the question of how you get a sharp subject. I feel composition is an important aspect of focusing your eye on a subject. You'll want a background that adds to or at least does not detract. The arrangement of the subject within the field helps, and decisions in this regard are not always the most obvious. Of course, a sharp focus is usually desirable. Volumes can be written on each of those subjects. Today we will talk on background. The tuckahoe is kind of a messy plant, growing in water, with stems that go every which way. Here I was able to isolate the flower, with shaded water in the background. Absolutely none of that mess to distract. Then on the computer, the contrast is bumped up a notch, making the background even darker. The tuckahoe itself helps as a focus of interest because of its unusual look. Tuckahoe grows in shallow water in AL, AR, CT, DE, FL, GA, IA(E), IL, IN, KY, LA, MA, MD, ME, MI, MN, MO, MS, NC, NH, NJ, NY, OH, OK, OR, PA, RI, SC, TN, TX, VA, VT, WI, WV, ON, and QC.
