Thanks, Peter! That was chance. I was in Prague on the main square early morning. This couple was desperately trying to capture each other without a flash in very low light conditions. I came for rescue, but could not get anything convincing with their camera. Have taken pictures on mine instead. However, I have written his email with mistake, it seems. I have got no reply after sending them the pictures. Pity, really.

Prima, der verliebte Blickkontakt zwischen den beiden!
Viele Grüße und schönes Wochenende!
Peter
