According to a national study, 92% of vacation photos consist of at least three pictures of sunsets. OK, we made that up, but it sounds about right, and so we suspect that Canon will be on the receiving end of oodles of sunset shots as the entries start to roll in for its third annual "Photography in the Parks" contest, which challenges legal U.S. residents over the age of 13 (perhaps there are separate such contests for children and/or illegal aliens?) to submit their shots taken in the vicinity of any park or monument in America. This year's theme is "inspirational nature images." Translation: sunsets!

The grand prize has an intimidating ring to it: "an unforgettable vacation for two in the American wilderness." If that sounds too much like the tagline of a bad Chevy Chase film, aim a little lower. The three runners-up get Canon photo gear. What's the catch? The contest is not open to "professional photographers," which the Canon legal team has defined as "one who has earned 51% or more of his or her annual income by taking, selling, or marketing photographs, whether as an employee or as a freelance photographer." So consult your tax returns to make sure you qualify, and then get to snapping some sunsets. You've got until September 30 to enter.
