Themes Variations
After taking enough photographs, a photographer often develops a preference for capturing certain types of images with certain themes, using certain equipment, and with certain style. The "certain" aspects of that process aren't always that certain, but images start to become similar. In the best of all possible worlds, "similar" doesn't degrade into "tedious".
I've developed a particular interest in a variety of subjects and styles and themes. You'll find examples of that work, in this section of the online looking glass gallery.
