I'm new at this. This is an astounding thread! I want to make my small contribution to it.
I have taken the corridor image and made elevation views of it in Hugin. I don't know if it really adds much knowledge other than the sense of space and proportion.
FYI - The camera position is at the midpoint on the left side of the deck view.
... argh... it looks like I have to post them to my website first and link to it. I will have to report back when I get that done.
(apologies--it's my first post)
