Mirror.co.uk has a short article on the very first picture of Daniel Radcliffe from the Deathly Hallows filming. They say "The mist thickens around wand-wielding Daniel Radcliffe in a forest scene from Harry Potter and the Deathly Hallows."
The picture feature Harry walking around in the forest--looking REALLY old. Yeah, no kidding. Maybe it's the angle of the shot...
Thanks to Snitchseeker you can see it here.
