“Stacking” will have no effect on depth of focus.
Oh, but it does. It is called focus stacking.

Frank, technically, it doesn't have any effect on DOF. That is a characteristic of the lens and remains constant. Focus stacking will take numerous slices of focused portions of the scene and place them together to render the scene with a larger focused area than the lens itself could render.

A tilt shift lens is probably the best way to get more things in focus on your diorama. It is the most expensive way, but gets it done in the camera. And they are just really cool lenses.
Sold.

The difference between depth of field and depth of focus is explained in the link I posted on the first page.

Got me. Yes they are different, but the same things controls both with one exception. That is why (I think) most of us (including me get confused sometimes) and call DOF as depth of focus....we think in terms of what is in focus from start to finish/front to back, or how deep is the focus.......Both are controlled by lens and aperture, while depth of focus can also be controlled by tilting the sensor or using a tiltable lens...
Here is another good explanation of both for anyone interested. it also has a lot of pics showing it... https://www.edmundoptics.com/resources/application-notes/imaging/depth-of-field-and-depth-of-focus/
Thanks for slapping my hand guys.......I need to learn to be more careful when using the terms. DOF is depth of field, not depth of focus. that's why we get confused sometimes...

A question in my exam paper reads..."Explain Depth of Focus" If my answer was about the merits of ...' Depth of Field' ..I would have failed on that question, and possibly the whole paper. So, in 'My real life ' It made a LOT of difference............ Have a nice day.
