A few years ago I learned about Photography Corner. Photography corner is an amazing resource for photographers of all levels of skill. An important resource on the site would be the Articles by Amy. These are articles that are written by Amy Renfrey who is the author of the e-book Digital Photography for Success.
Amy’s knowledge and easy writing style are very helpful to digital photographers, whether they just be starting out or are seasoned professionals. I read a few of the articles so far and think that they are Great Photography Articles that you should be sure to read.
