The National Geographic Traveler Magazine photo contest, now in its 25th year, has begun. There is still plenty of time to enter. The entry deadline is Sunday, June 30, at 11:59 p.m. Entrants may submit their photographs in any or all of the four categories: Travel Portraits, Outdoor Scenes, Sense of Place and Spontaneous Moments. The magazine’s photo editors showcase their favorite entries each week in galleries. You can also vote for your favorites. “The pictures increasingly reflect a more sophisticated way of seeing and interpreting the world, making the judging process more difficult,” says Keith Bellows, magazine editor in chief. (The captions are written by the entrants, some slightly edited for readability.) As always, you can take a look at last years winners.
