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)



Yeahbut...

The common expression "Stop Down" really does mean to
reduce aperture size (although it also means a higher
F-stop number)...

Thinking about it since, I'm sure that's what Gunner meant.


Correct. Historically...the bigger the number meant the smaller the
hole. 1 is on the top....64 is on the bottom...when you "stopped
down"...you were going farther down the list..and making the hole
smaller...letting in less light...

Im just an old fart.
