Pembroke window

A window of Pembroke College. While it's a nice enough window, I actually wanted the picture to home my Photoshop skills a bit - the original version included various vents and people. Interestingly, the three things that to my eye look the most artefactual (the circular bricking round the top right of the window, the paler stones to the right and the darker area round the bottom that looks damp) are all original.
