inthedark,

Yeah, I should have mentioned that these enalargers also have lens stages that tip and tilt.

I came to this business after having a fair experience in Large Format photography - so it all made sense

Yes, the person in the practice is a photogrammetrist ( two m's - no doubt from some arcane language rules).

At the place I worked prior to starting my business, we had a monster Robertson Tri-color overhead process camera. It was put in the building and the walls were built around it. The Acti line is much more advanced and accurate.

Best of luck in your operation - we're booming out here ( left coast).

Later,
Terry
