et hop !
On Apollo 8, Hasselblad EL electric cameras were used for the first time. The electric motor in these Hasselblads largely automated the picture taking process. The astronauts needed only to set the distance, lens aperture, and shutter speed, but once the release button was pressed, the camera exposed and wound the film and tensioned the shutter. Two Hasselblad EL cameras, each with a Planar f 2.8/80mm [normal] plus a single Sonnar f5.6/250mm [telephoto] lens and seven magazines of 70mm film, were carried. The cameras, film magazines, and lenses used on Apollo 8 had black anodized surfaces to eliminate reflections.
le seul appareil où l'on mentionne du blanc est ici !
In addition to the Hasselblad cameras, Apollo 8 carried a black and white television camera, a 16mm motion picture camera, exposure meters, several types of filters, and other camera accessories.

The outer surface of the 500EL data camera was colored silver to help maintain more uniform internal temperatures in the violent extremes of heat and cold encountered on the lunar surface. Lubricants used in the camera mechanisms had to either be eliminated or replaced because conventional lubricants would boil off in the vacuum and potentially could condense on the optical surfaces of the lenses, Reseau plate, and film.
