Here are a couple of websites that offer informative lessons in digital photography techniques, such as sharpening and creating custom borders. Definitely worth bookmarking and browsing during a coffee-break or two (found via digicamera.net and Photexels).

Website: Petteri’s Photo Lessons
“By popular request, here is the web version of Petteri’s Photography Classes. These lessons were first published on the Minolta Forum at Digital Photography Review. For the web work, I’ve edited the texts, cleaned up some of the graphics, and set up this framework into which to plug them. Enjoy!”

Website: Russell Brown - Tips and Techniques
“Welcome to the official, and experimental, Russell Brown Tips and Techniques page. This is your one stop shopping location for the latest in hot new tips right off the silicon wafers. In the effort to stay on the cutting edge of technology were offering QuickTime movies of some of my favorite tips. In some cases we will also offer a PDF document to accompany the movie. Beware, the movies are large and will take time to download when using a slow connection. These movies have been optimized to download as fast as possible and still look good in most cases.”
