About Digital Photography How To

Digital Photography How To is intended to be a guide to people learning how to use their digital SLR cameras. Three years ago, I had never picked up a camera; now, I produce a yearbook every year and I moonlight as a professional photographer.

I write this website to share what I've learned in that time. The topics will range from truly beginners topics, to tutorials for post processing, to resources for yearbook and graphic design, to thoughts on transitioning from a hobbyist to a professional. Keep up to date by subscribing to the RSS feed.
