work on the principle that I'm going to have lees DOF when working in MF
and a little more with APS-C digital. Yes, print size theoretically
affects DOF, but standard viewing distance does too and that cancels it
out as far as I can tell.
My CoC/DoF rules of thumb:
1 - Go by what's on the lens' DOF scale
2 - If it's a critical job, keep things slightly *inside* the range on
the lens' DOF scale
3 - The DOF you're going to get is pretty much set at the moment your
three-dimensional scene is turned into two dimensions on your film or
sensor, so get it right at that point
4 - "Go out and take some pictures" (Doug Brewer)
All above can work in practice and is very close to my behaviour too.
However, Shel asked a question and I tried to answer as I could.
With due respect, why all those who are not interested on a given discussion
just don't stay out of it and keep participating to the topics they are
intersted in?
All the best,
Dario
