A large parabolic reflector would work just fine. From Clavius' own description: Clavius - the truth behind the moon landings: http://www.clavius.org/bibzz1.html The filming was done at night, so that sunlight would not intrude. The lighting was provided by a single 18 kW studio light placed so that it would illuminate a patch of ground 150-200 feet (50-70 meters) away. At that distance the light rays -- while not exactly parallel -- are close enough that the error in shadow "lie" on the surface is less than the "noise" created by the irregular ground (1). NOTES 1. At a distance of 200 feet the angular error in lighting direction per transverse foot is 0.29°. That is negligible for most of the camera angles used in the reconstruction. Once a light source is sufficiently far away, it behaves more like an infinitely distant light than a nearby light. You mean this quote here? The subject of the photo is always illuminated and then the light intensity quickly falls off as you move toward the edge of the photo. That is not an opinion - that is a fact! It's Not!
