As I’m learning the stock photo business and exploring new angles in photography every day I have been slowly gathering up my “go to” list of sites for quality photo insights. Here’s my latest list:

• Photopreneur
  This is a great blog specifically about building your knowledge as a professional photographer. The articles are well written and concise.
• Derek Powazek
  Derek offers a unique perspective on the trends in the digital creative world and is well hooked in to the popular flow of things happening on the net.
• Microstock Diaries
  A microstock specific blog with great tips. Mandatory reading if you’re getting started.

Of course, when you’re poking around each of the microstock sites (my list) you can always explore their forums, faq’s, and feedback as ways to improve your craft. The most important thing is don’t be afraid of rejection! Photos get turned down all the time.
