Panoramic photograph of the inside of one of the archways of the building that separates the Cathedral / Minster Yard from Castle Hill in Lincoln.
The first image was begun a the bottom looking through the arch and the “aperture size”1 has therefore come out too small to record the vaulted ceiling.
The second was begun at the ceiling so the archway itself has come out too bright.
The combined effect is that you have all the data you need to process an image in your own mind as to what the arch looks like:) Hey presto (etc).
PS sorry about the scaffolding. We are having some work done.
1 If that’ how you put it – I’m no expert on photography. I just know what I like 🙂
