Jim, I noticed in both of these recent images that you are photographing at an oblique angle and not swinging the back and shifting the front to correct the line convergence/divergence. I am not familar with the 2D...perhaps it is a condition of that camera and it doens't have the required movements. Maybe I am just being nitty picky.
No not nit picky. I was a bit sloppy. Had forgotten the good level at home and was trying to work from the little "swinging arrow" that's built into the old cameras.
