Been wanting to shoot this cathedral for years, but they always told me no, along with every other photographer that asked. Fortunately I took on the lighting designer as a client and he got me in there for two half days. If any asks, I shot all of these for him.
For the two shots up the Nave and the shaight-on shot of the sanctuary, I used no additional light, just good timing. The others had some tungsten lighting. Also, for the sanctuary, my client coated the windows with a purple film so the sanctuary would glow purple during the day, which I thought was pretty cool.
