Not a perfect shot but still arresting (a slight breeze made focussing tricky). I was surprised to see that at the London Wetlands Centre, Barnes, http://www.wwt.org.uk/visit-us/london that there are still some fine wild flowers hanging on in the meadow areas. I love going to the Wetlands. It is a truly marvelous re-creation of different wild environments as they are found around the world. There is also the benefit that as more and more birds discover and populate the centre they also visit the neighbouring areas as they fly around, exploring London.
For the technically minded: Lens - Olympus 50-200mm at 200mm (equivalent to 400mm on 35mm format) set at maximum aperture f3.5 to get that marvelous defocused background and the unrivalled Olympus in-camera processed jpeg colours. Camera: Olympus E3.
