Thanks, Vladlen, that all makes perfect sense. I’ll start paying attention to the reprojection error after triangulation to compare against various shooting conditions in better training my eye how best to shoot.
Götz, I’ve only run the chair in High and Preview, might be interesting to now see what difference there is in Normal. The issue with holes in the wood carvings should present a difference, given my 52 MP Sony A7rii shot the chair from 1.5 m will plenty of light to sustain high dof.
Make real hay in the meanwhile, I’ll follow up.
Many thanks, both of you.
