I started doing photography around 2007 or 2008, began to regard it a little more seriously after 2013, and have been taking it a good deal more seriously in just the last couple of years. It was originally very much a hobby, unconnected with what was then my full-time job teaching law at the College of William & Mary in Williamsburg, Virginia. I'm now a retired law professor, though, and spending more time both on taking pictures, and on editing, sorting, tagging, and displaying all of the ones I've already taken.
Cameras with film never interested me much, but when digital photography became affordable and I bought my first, 3 megapixel camera, I felt free to snap away like a madman. The near-instant gratification of digital imagery and the disappearance of film costs motivated me to take up the hobby. (I didn't foresee what I'd eventually end up spending on good cameras, lenses, and printers, though, or else I might have reconsidered.) Plus I like working on my computer to polish and perfect images; they're rarely everything they ought to be when they first come out of the camera.
Currently, I'm working a lot in black and white, using mostly close-in shots of growing things. I'm also venturing into a bit more abstract work, though nothing I'm ready to show publicly yet. The trick with black-and-white photography--at least for me, a person who has always been, and still is, strongly attracted to rich color in photography--is to learn to recognize what sort of images will work in monotone, without having to do what I do now, which is a lot of trial and error; but that's coming slowly. Eventually, I hope to be able to do appealing black-and-white work with a few fewer trials and a few fewer errors. That'd be good.
