Photography, after all is the play of light on objects, and so naturally light is a major aspect of taking pictures, and we often don't pay it enough attention. What I would suggest, now that we are in the age of digital cameras, is that you play with the exposure and aperture settings, and pick one that you think says it best. All of these photos are examples of doing just that, with one major exception, and that is the seagull picture, where I didn't have the luxury of time, and so I just kept shooting, and hoped one or two would turn out. Enjoy them, I know I did.
