大岩壁攀登者真实瞬间

2x2 grid, 16:9, do this for 4 different subjects and scenes input = [ climber(s) / wall_context / move_beat / capture_medium / rope_and_gear_law ] run big_wall_alpine_rope_truth: subject_dna := a climber mid-move — hips pressed to the rock, heel raised on a tiny edge, fingers crimped or jammed in a crack, forearm tendons and veins standing out, chalk on the hands and smeared on the holds, taped knuckles, a bloodied fingertip, real strain in the face context_dna := infer granite, limestone, or alpine mixed ground; real rock structure — cracks, flakes, chickenheads, lichen, water streaks — never a smooth blank surface moment_state := the committing move + causal_hint (reaching for a hold, placing a cam, weighting a foot that might slip) capture_dna := shot from a fixed line above or a drone at the same height, 24–50mm equiv, deep dof, hard high-altitude light, fine grain focal_anchor := the hand on the hold or the gear placement — tack-sharp; the void below dissolves light_logic := hard high-altitude sun with an extreme dynamic range, deep unfilled shadow in the corners and cracks, warm bounce off sunlit granite, a cool shadow side, thin clear air imperfection := the rope swinging out of frame, wind lifting a jacket, a slightly awkward real body position rather than a heroic one, gear racked untidily depth & frame := void below — hundreds of metres of air, the ground lost to haze or absent entirely, a partner or portaledge as a tiny speck for scale; vertical 4:5 emphasizing the drop rope_and_gear_law := the rope must attach to a real point — tied through the harness belay loop, running down to the last piece when leading or up to an anchor when top-roped; it sags in a catenary curve when slack and goes dead straight and thin when loaded; cams and nuts sit in constrictions that could actually hold them; quickdraws hang under gravity; the harness bears visible weight mood := exposed, focused, deeply committed render: one honest instant where true rope physics and real gear make the image. forbidden — objects: ropes attached to nothing, missing harness or anchor, invented gear, a blank featureless wall with no holds forbidden — look: a rigid straight rope with no weight, rope floating away from the body, relaxed effortless posture on hard terrain, gym-flat lighting on an alpine face, no exposure below, clean unchalked hands
