Elijah Wood has become an avid photographer over the last few years, after getting into the habit of taking snapshots on his movie sets.

The 24-year-old actor started taking photographs of his work in progress as he shot his hit Lord Of The Rings trilogy in New Zealand, and he's continued to do the same on all of his movie sets.

He says, "I have boxes of (pictures I took on the Lord of the Rings set). They're sad, in a way. I was 18 years old when we first started shooting, and it had such an impact on me as a person - it was massive. So looking back now is somewhat nostalgic.

"I generally don't tell people I'm taking photos of them. I'll just capture moments. If someone starts laughing during a conversation, I'll take a photo, so that it's spontaneous. And the camera is so small, I never make a big deal out of it."
