Here are links to my effort to combine the two scans of the corridor from TMOST. Suprisingly, I had to disproportionally scale one or the other to get them to match. The difference in contrast on the left side shows where I chose to mate the two. Actually I overlaid the two so that the arches were the same size and position.
I find it interesting (or bothersome depending on if it is not really so) that the arch is NOT at a right angle to the corridor wall in either the TMOST shot or the color screen cap I worked with. Anything is possible on a set to get the shot, but how would that help here? I don't know. (I hope my thumbnail/links work.) +RK
