Cathedrals are big. Moreover, the space around them is often limited. Consequently fitting the building into the viewfinder can frequently be a challenge. If you haven't got a very wide lens then you either have to accept massively converging verticals or you have to move back as far as you can. On the evening of our visit to Salisbury Cathedral in Wiltshire, a building with a much larger "close" than is usual, this was the position where I could just about get the verticals to be vertical, with the trees making a dark, detailed "frame". This building was erected relatively quickly compared with many cathedrals. The main body of the church was built between 1220 and 1258. The chapter house was added around 1263 and the tower and spire were completed by 1320. Incidentally, it's the height of that spire, Britain's tallest at 404 feet (123m) that accentuates the photographer's problem described above.
