With everything so correct did you use perspective correcting lenses? And a view camera I presume.
No, perspective correction was done in my post-processing using Lightroom. My camera in 1980 was a Nikon film SLR (a NikkormatFT, I think) and probably using a Tamron 28-200mm zoom lens. In 2000 I was probably using a Nikon FE with the same lens. (That was a long time ago and I've changed cameras several times during that interval.)
