First, all those who commented: thank you, and in particular, drpsilver, thanks for commenting on the technical issue. Airbubbles, I think that sounds like a good explanation, I'll keep investigating. After holiday, a few weeks of work and another weekend away, time to comment on cards received since my last post. Mike c, sycamore trees, dreamy shot, great shapes, great light. LarsAC, barn door, well, lovely shot, and quite close to my birthground, just 40 km away. Funny to see a photo taken in Zeeuws-Vlaanderen. Black Dog, chance and random things, looking into the Anthropology shop and at the same time looking across the street, reflections in the window. Great. First colour shot in quite some time. Neil from Harman, Just clouds. Well, yes, that works out very good as a subject. Nice and contrasty.
