We actually only got around half an hour to photograph because of an unexpected ordeal to get a permit. It turns out that you need a permit if you are going to use a tripod inside the Cathedral, so bear that in mind if you are planning on doing anything like this. It cost a fiver to get the permit and by the time we were done with that, we didn't have as long of we wanted to photograph. Another thing to take into account if you go here is that you cannot take any images if there is a service, you can't use flash and you cant go to any parts where there is currently a private service taking place. To the bottom right of the image, there was a small chapel which had a christening happening and so we couldn't go over to that area of the building.
Here's another image from the morning. Actually, this is the first image that I took. The hardest part of this was finding the very centre on the floor and as you can see from the slight difference between the upper triangles on the very left and right and the lower ones. However I don't think anybody would actually notice this, as most people aren't as picky as me! So what is probably the first thing we do when we walk into a building like this... look up! And I found myself doing exactly that, therefore I decided to take this photograph. With some slight cropping and perspective warping I have got it as close to symmetrical as I think I possibly could.
