Taken just outside Hathersage in the Derbyshire Peak District, this image used a shallow depth of field to isolate the silver birch in the foreground. I happened to like the green grass in the background against the browns of the bracken.

The technical bit:
Camera - Nikon D800
Lens - Nikon 70-200mm f2.8 @ 200mm
Aperture - f2.8
Exposure - 1/800 second
ISO - 100
