At SportsShooter.com I found a very interesting section SportsShooter.com: Student Portfolio. This section is dedicated to a contenst of student portfolio, as you already may guessed. The most important part is though not the pictures, which are very interesting by itself. But the comments, which are posted by professional photojournalists and sport photographers. By reading those comments and evaluating the photographs you may learn a great deal. So, I would really recommend to take a look and add the link to your bookmarks.
