In these circumstances, the way to get good depth of field without stopping the aperture down so far that pictures lose definition is by focus stacking.Д«ecause we donвЂ™t need to worry about getting a deep depth of field with a single photo, we can instead consider how aperture can be adjusted to produce a high-resolution, high-definition image with each shot. And stopping aperture down increases diffraction, resulting in pictures that lack definition. Given the same aperture and a lens focal length chosen to produce the same picture angle, the large image sensors in FX format cameras and the like will show a shallower depth of field than smaller sensors, so you really have to stop the aperture down to get a deep depth of field. When it comes to focus stacking, it might seem natural to ask, вЂWhy go to all that trouble when you can just stop the aperture all the way down?вЂ™ but itвЂ™s not that simple. This is precisely the sort of difficulty the D850вЂ™s вЂњfocus shiftвЂќ feature, which automatically varies focus by a set amount over a set number of shots, was designed to solve. It used to be hard to change focus by the same amount with each shot, and unless you finished shooting quickly, there was a chance that the light would change or some other difficulty might arise, resulting in photos that were not suitable for focus stacking.

Specifically, what was difficult was taking a series of photos while changing focus a small, fixed amount with each shot.

Although dedicated focus-stacking software has been around for a while, the hard part was getting suitable high-quality image files.

The technique of focus stacking allows you to enhance the depth of field in an image by taking a series of shots and generating a composite image consisting only of the areas that are in focus. The D850вЂ™s handy вЂњfocus shiftвЂќ feature is used chiefly to create the images for focus stacking, which are then combined in optional third-party software to create a final image with extreme depth of field.
