You have hit on my exact problem. I was taking a picture inside an
old prison cell in the Walls Unit in Huntsville, TX (in the 19th
century building). ( I saw the "hole" there, by the way. It was a
closet (as you may know). It was smaller than 5x8. I took a picture
of it, and that one turned out fine. ) Anyway, back to the cell. I
was trying to take a picture of the sink and toilet, right next to
each other. Evidently I over-adjusted for bellows extension in the
tight spaces there, and the print was way over exposed. But I think
now I understand why: i was using expodev wrong.

I should have been contemplating autocollimation. Sounds like
something that might be sin in Catholicism, as well as within the
Texas Dept of Corrections system.

Solidarity forever.
