Far too late I know, but incase anyone else wants to know because I am constantly in the New Forest area, there is an amazing campsite "Hollands Wood" where you can wander off into the woods and catch some great landscape shots with the Ponies, it also has some great lakes scattered about, if you follow the river down at Balmer Lawn you can get some great locations off of the beaten track.
Just along the road you have Beaulieu which is beatiful for landscape shots and the motor museum their is great, just up from their you have Bucklers hard which is a great location for old style photo's with a museum setup of houses, get the river boat down Beaulieu River and you can catch some great photos of the fish jumping out of water.
All around that way is great, Christchurch is not too far down the road where you can go to Highcliffe castle.
Sorry it's all too late now but if anyone else is wandering that way there is an abundance of Photographic scenes and things to be shot.
