A reader at CountingDown sent them this:

"...Arriving just as the cast and crew were leaving to have there lunch I managed to get hold of one of the security guys and ask what scene was getting filmed - he said 'it's the one with the executioner' however if it was the executioner scene why didnt myself and my friends see the lovely Ron? Maybe it was one if the time turner scenes with just Harry and Hermione...

...Couple of hours past and we could see an odd glimpse of Dumbledore and his massive white beard, nothing really exciting apart from when we could hear the faintest sound of ' ACTION ' and ' ROLLING '...

...As filming drew to a close the jeeps were back in action, shuttling off Dumbledore...to his hotel. Then it was the turn of two of the main stars, first Daniel whom you couldn't really get a glimpse of but a hand and toothy smile gave it away and then Emma who again smiled happily and waved until we could no longer see her...

...Overall, you couldn't really tell much of what was happening at the set, although asking the security guy did help. They are also filming the werewolf scene up here at Loch Eilt near Mallaig but no idea when!! The scenery up here is fantastic and will be absolutely gorgeous in the film..."

CD reader took some great photos of the set as well:
