Last call to enter to win cash and prizes, and have your images published in Scuba Diving magazine.

The April 20 deadline is fast approaching for Scuba Diving’s annual photo contest, and we are still looking for entries in every category. We know you’ve been out there on the front lines diving some of the world’s top sites, and we want to feature the images you’ve taken. If we choose your image as a winner in one of the categories, you could receive prizes ranging from travel and gear to cash and cameras. Plus, your winning shots will appear in the August issue of Scuba Diving magazine.

Enter in one or all four categories — including traditional Macro and Wide-Angle, and two new categories for this year, Behavior and Photo Essay — in which you enter six images that tell a story about a specific destination, dive site or encounter. Go to scubadiving.com/2010photocontest for the official rules and entry form. (UPDATE: to enter online, use this link instead)
