Thanks for your comment, Michel Yes, they were dancing on the Strauss Waltz. First I take the pictures underneath the plexiglas, while I was watching the show from my lounge-chair. One hour later they did the same dance, and I take the pictures from outside. Mixed the pictures together for my first presentation. It was not as easy as I thought, but PTE is a nice program and I am sure: more presentations will come! Jan Hordijk
