That wasn't me but I can explain. Stacking is where you take several images moving the plane of focus incrementally either using a focusing rail or by adjusting the focusing ring. The results are then combined into a single image using stacking software. The two "industry leaders" are Zerene and Helicon Focus. The idea is to shoot at a mid-range aperture that represents the most sharpness of the lens. The software takes aslice of each subsequent image using the portion within the narrow DOF. It is typically used with close-up or macro images where the DOF is quite narrow. As a sidebar: I use Helicon Remote which is the tethering software to capture the set of images and then use Helicon Focus to combine them.
