According to Wikipedia, the online and free encyclopedia, photography "is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film."

Various categories of photography include: portrait, wedding, still life, sports, nature, wildlife, architecture, macro, and astrophotography. Over the years I have dabbled in all of the above and more but these days most of my time (and my camera) is focused on nature, wildlife, macro photography, and behind-the-scenes, special effects.
