I finally started experimenting with it (macro).
What I learned:
D850 starts stacking, focusing from the closest focus point. If you want the best result, use your lens optimal aperture setting.
When doing macro, you must use a tripod.
The camera setting depend on the scene, so the stack focusing must be adjusted every.single.time.
Setup:
► Menu
► Photo shooting menu
► Photo shift shooting
→ Number of shots: 1~300. Front to distant. You need quite a bit in macro.
→ Focus Step width: (1~10) Distance change between shots. Low value create small steps, large value, well large steps. At issue is if the steps are too large, it will create issues in sharpness when stacking.
→ Interval between shots: In seconds. I usually set to 5 seconds, this reduces all vibration that may have been generated during the previous shot. If you have a great number of capture, time to fetch a coffee or take a quick nap, your choice.
→ Exposure smoothing: Exposure will adjust between each shot. Great outdoor, If indoor with controlled light sources it is useless. Note, the flash will not fire if selected.
→ Silent photography: it 'silence the shutter' during shooting. Use 'Mirror-up' instead.
Warning: Due to the number of shots flashes that depend on batteries will stop working quickly.
When ready to shoot, after focusing on the closest point from the camera
► Turn on live view
► Manually focus the first capture on the closet focus point. Use the magnifier to adjust/verify the focus.
► Turn off live view
► Set Mirror-up (Stability)
► Open menu
► Photo shooting menu
► Start
Stacking software you may want to use
Helicon Soft: Helicon Focus
Zerene Systems: Zerene Stacker
Adobe: Photoshop CC
(There is a complete list of stacking software in the post-processing forum.)
I know nothing about this, but I find it interesting. So the camera automatically changes the focal point? If so, then it can only be done on certain cameras, correct? Will the camera “stack” the images by itself? Or must a computer program be used to create the final image? Sorry for all the questions. Thanks!
The D850 will change the focus as it takes the images. You set the parameters. You must use external software to do the stack.

Flashes will not fire with silent on. Best use constant light when taking many pictures.

I think he means when Exposure Blending is chosen only. With macro being one of the focus stacking most uses (I think), it wouldn't make sense that you couldn't use a flash.

No. The camera does not do the stacking nor the blending.
Exposure smoothing allows the camera to control the exposure, ISO and Speed. This feature avoids issues when working outdoor using the stacking option. It makes sense as if you have the camera shooting for two, three minutes anything can happen during this period. This is useless in a studio or where the light is controled.

Use Exposure Delay mode?
A different beast that does not allow for stacking - for depth of field -. The mode purposes are entirely different.

The camera produces seperate images at each of the calculated fucus distances. Stacking is done by combing the seperate images in a post processing software package (like Photoshop), not in camera.
Thanks for the explanations!

To do that one needs an Olympus. 😀

Why turn off Live View, Ron? When I select Menu > Focus Shift, doesn't it just go to mirror up shooting?

Because the camera release the mirror first.
