I'm in Winsor's camp on this, which makes me sort of wonder why I got into this
discussion to begin with. I rarely consult the DOF marks and wouldn't miss
them if they were gone. Determining what's in focus and what ain't is what
viewfinders and DOF preview buttons are for. If a camera's viewfinder is not
good enough to allow me to see this clearly, that's not a camera I'll use.
For those who are otherwise inclined and want to figure this stuff out, there's
a free DOF calculator you can download from the Digital Light & Color website.

There's also free software there to calculate the correct scanning resolution,
which I find more useful. Then there's another free program that calculates
the time of sunrise, sunset, moonrise and moonset. Since I have abandoned my
werewolf ways, those times are of little concern to me now, so I seldom use
that one, although I do sometimes start feeling a litte hairy when the moon is
full.
