A two-panel before-and-after diptych, split exactly down the center by a thin subtle vertical seam, both panels equal in width. The same woman appears in both panels, standing in identical pose, identical framing, identical distance from the camera: full body, facing the camera directly, feet slightly apart, arms held a little away from the torso so the whole silhouette is readable, neutral expression, head level. Photographed from eye level at roughly 50 mm perspective with deep focus, so both figures are equally sharp. Same seamless mid-grey studio backdrop with a soft floor line in both panels.LEFT PANEL: entirely human. Natural, fully human body with believable skin texture, visible pores, fine arm and leg hair, uneven skin tone, faint veins, bare shoulders, arms and legs, wearing only a plain heather-grey sports top and short leggings. Slightly soft human musculature, real knees and elbows, human hands with natural nails, loose human hair falling over her shoulders. Warm reflected skin tones against the cool grey backdrop. Soft large key light from camera left, gentle fill from the front, thin cool rim light from behind camera right, creating a faint natural shadow to her right.RIGHT PANEL: the same woman, same body shape, same pose, same height and proportions, now almost fully robot. Her continuous outer surface is machined metal plating: brushed aluminum shoulders, gunmetal steel chest and abdomen panels, visible segment seams and hex bolts, exposed hydraulic pistons along the thighs, carbon-fiber forearms, articulated finger joints with visible servo mechanisms, split knee and elbow housings, cable runs tucked into gaps, faint amber and cyan light glowing from narrow vents between plates. One remaining human element: the left half of her face stays human skin with a human eye and a few strands of real hair, while the right half of the skull is a smooth chrome plate with a single lens eye. Everything else is machine. Cold steel, titanium, matte black polymer and oxidized copper accents, cool blue-grey palette with small warm glowing indicators. Identical lighting direction and shadow placement as the left panel.Documentary-precise, photorealistic studio photography, physically plausible materials, realistic reflections and contact shadows, restrained grain. No text, labels, captions, arrows or typography anywhere in the frame. Only one figure appears in each panel.
