Enter the Profoto Portrait Challenge and you could win the world's smallest studio light

Your best people shots could win you a Profoto A1 – one of the most exciting lighting innovations of recent years. Win one of the four rounds, each with its own prize, and you're in with a chance of netting the Profoto A1 as the overall winner of the Profoto Portrait Challenge.

In each round, you can submit up to three portrait shots; they're judged individually, not as a set. And if your work is judged to be the best, you'll win a prize. The overall winner will be chosen from the four round winners by the experts at Photography News and Profoto.

For full details go to the competition page.

The first round is open, and the theme is beauty. So choose your top three images and enter now! You've got until 7 June to enter round 1.
