The Nikon D850 has a automatic focus stacking utility, which thanks to Steve Perry of Backcountryphotography.com, , I figured out how to use. The image of Mesquite dunes is a stack of 17 exposures done by the D850. Camera was about 12" off the sand, about 30 minutes after sunrise. Cropped, exposure, etc adjusted in Lightroom and finished in Topaz Adjust in Photoshop.
Nice result …
Now that’s stacking done well
