Of course if you can't take an incident light reading at the subject or under equivalent lighting, you are absolutely right that a spot highlight reading is best. I'd stick by my assertion that incident is usually easier, though.

The first commercially successful spot meter (SEI Photometer) didn't even bother with a mid-tone/18% index, just shadow (for negs) and highlight (for trannies and film). The only thing that stopped me including all this was that the original post was already pretty long...



Don't forget for dynamic range, many of us in particular that shoot transparencies, and to a lesser extent negatives, will use Graduated ND or colored filters which will allow us to stay within the acceptance range of the film.
