Am I correct that Headshot 1 is importing a photo to create a 3D face, and Headshot 2 is importing a 3D scanned face to mesh?

If so, is it possible to get better quality from a scan than from a photo (PRO)?

Ability to create from photos in Headshot2

is the same as Headshot1. 2 is just that the function that can be created from the scan model has been added to the function of 1. Even 25.75 million polygons can be loaded and detailed normal textures can be created.
