resolution of the microscope."
I'm sure I'm missing something by my failure to completely comprehend
the difference between depth of field and depth of focus, but several
introductions to photography just use the phrase "depth of field",
even though it could mean "depth of focus". I've tried to simply the
problem by using the phrase "the space where everything is
visually sharp" when I talk with layment. But, of course, I'm sure
many technicians would object and would ask me, "You mean depth of
field or depth of focus?"
