I am a professor of Biology and Biophysics at Johns Hopkins University. Despite never having displayed significant artistic abilities, I have always been sufficiently interested in art and design to have worked on my own at developing my limited abilities. Thus, I did some photography as a youngster, did more during my post doctoral studies, then turned to graphics and learned Adobe Illustrator so that I could draw all the figures for two of my books, both of which I designed (consulting with the publishers' artists). As I'm not now writing a book and also no longer have a need to design and build our household furniture, my artistic creative urges are currently being satisfied with trying to improve my photography. When I returned to photography, about five years ago, I spent a year or so learning the technical aspects. Now, most of my effort goes into the artistic aspects. Contrary to my maxim of trying to use the best tools, I do not use Adobe Photoshop. I happened to have gotten started using a program called Picture Window Pro, which is very powerful, and operates at a rather fundamental level.
