Exposure compensation and zone system - am I thinking correctly?

[Q.G.]

I think tkamiya has it correct now, just as eddie suggested.

Opening the aperture for exposure correction may help in explaining it to students, but it has the disadvantage over time corrections that it changes the image's depth of field. Hence, exposure corrections through shutter timing adjustments are preferred, because they do not alter the image.

Spoken as a true still-life photographer...

(I know, i know: you do you take photos of living matter. But that statement... )


Photography students should know that both shutterspeeds and f-stops determine exposure. It's about the first thing they need to know and understand. You can't even begin talking about the ZS if they don't.
So a rather strange thing to say, Eddie.

Of course, when I taught, we had already gone over the relationship between shutter speed/f-stop before moving into tone placement. I should have mentioned that but, like I said, it was a long time ago...

I just would have thought that at that point, all you should need to say is to give it 1 stop more or less exposure, assuming they should know how to do that.
