True indeed. Low f-stop and slow shutter for a minimum depth of field.



I think you have that backerds, hoss.

Higher F numbers mean smaller aperture diameter.
Depth of field increases with f-number

Reducing _aperture_ increases depth of field.

An shutter speed is not involved (directly, anyway)

Ahum...an F1.8 has a very low depth of field. An F16 has a far far
greater depth of field.

And under low lights...a slow shutter speed would be indicated (with
film and some digital sensors)

I suspect you are going by the hole size..not the numbers which is
where most folks work from.
