Cavalier lunaire surréaliste

A surreal black-and-white photograph of a {argument name="horse color" default="white"} horse riding an astronaut on the moon. The astronaut in a bulky {argument name="spacesuit color" default="white"} EVA suit is on all fours on the dusty lunar surface, acting like a mount, while the horse sits upright on the astronaut’s back in a humanlike riding posture with its front legs raised and bent as if holding balance. The horse wears a saddle and bridle with reins draped down toward the astronaut. The astronaut’s helmet has a dark reflective visor, and the figure is facing slightly right with hands and knees pressed into the regolith. The landscape is a barren moon terrain with scattered rocks and gentle low hills, under a completely black sky with no stars visible. Strong directional lighting creates crisp shadows and high contrast, mimicking documentary Apollo-era lunar photography. Center the paired subjects in a medium-wide composition, realistic textures, deadpan absurdity, photorealistic detail, vintage monochrome film look.
