Having spent the day photographing neighbouring Borough Market with a friend, we were heading home when he suggested popping in to Southwark Cathedral. I was ambivalent, agreed, but didn't bother to pay the £1 license to allow me to photograph the interior. One look inside and I headed straight back out. To contribute the paltry £1. What incredible value-for-money, not to mention for a good cause, that investment was. My eternal gratitude to the volunteer staff - what passion and knowledge.
