First Man's miniatures were, of course, just part of the bigger visual effects solutions. There are plenty of CG additions in the film, and the miniatures themselves were digitally composited into space backgrounds. But, starting some of the scenes with miniatures was a favorable way of acquiring a certain kind of image that can be harder to achieve with CG, according to Hunter. "You get these artifacts, these imperfections that are reality, and that you automatically get from shooting a miniature."
"In some ways, we felt like we were just documentarians," Hunter added. "We set up this shooting space. We set the camera up. We set up a light and we point the camera at the miniature and there it was, that's what we got. It's reality. There's no denying it's real."
