Rob Haggert's blog, A Photoeditor.com is fast becoming the best source for news about the photo industry. I log on at least once a week and there is always something interesting.
EditorialPhotographers. com is full of useful news and information on usage fees and estimating.
Finally, I was shocked to find how few students knew about the Eddie Adams Workshops. This is a free four day workshop in upstate New York that enables young photographers to work with some of the top photojournalists and photo editors in the country. Careers have been launched there.
