First slightly pointed upwards to somewhat avoiding the dominant reflexions on the water, then pointed a bit downwards to evaluate the intensity of the reflexions, and then guessing something like an average between the two as a basis for the bracketing: +2/3 — 0 — -2/3 stop, what I usually did with Provia as, to my personal opinion, a full stop was a bit too much of a good thing.
The best one was the '+2/3' as then the building came out a bit 'brighter', what was important to better show the aero condenser in the back, and the highlights (e.i. reflexions) were still 'acceptable' and could be handled by the fotogravure.
I let the photogravure (=chromiste) choose between the tree diapositives.
What you see here is a hardly edited home scan on an EPSON 750 of the '0' stop exposure as the good one (+2/3) was kept by the client.
This photo was taken at the end 1990's (and home processed in my Colenta AT60 machine).

Interesting, thanks. Having a Colenta at home is impressive!

Indeed, the complexity is one reason that this thread exists.

This is about a 5 stop range which is pretty much the limit of the Velvia 50 or Provia 100 that I shoot. Before I expose any film, I will hold in the metering button and scan the scene watching the EV difference from the average. If I don't find any other highlight and/or shadow area that falls beyond that -2.5 to +2.5 range, then I twirl the wheel to obtain the aperture I wish to shoot at, set the exposure accordingly, and expose. If I find an area outside the aforementioned range--lets say I scan across a shadow area that reads -3.0 EV that I care about (who knows why I didn't see that area in the first place!)--then I adjust my average reading accordingly and expose. This is all way more difficult to write about than it is to do...
