This tutorial doesn’t simply explain the overlap requirements or the classic acquisition techniques, but rather delves deep into more advanced techniques (for example, using a projected pattern to help the structure from motion phase) after first explaning even the basics of photography (depth of field, iso speed, etc.).
Sometimes learning 3d scanning is not just about learning the software: learning acquisition techniques and how to setup your devices (including your camera!) are essential concepts that are often overlooked.
