OK It's not really a photo of John, Paul, George and Ringo but I thought the title apt given the four trunks coming out of the same bit of ground. I found this wonderful silver birch high up in the slate mines in the Langdale Valley and felt compelled to capture it with the camera.

The technical bit:
Location - Langdale, Cumbria
Camera - Nikon D800
Lens - Sigma 35mm f1.4 DG HSM Art
Aperture - f1.4
Exposure - 1/2500 second
ISO - 100
