Create a photorealistic cinematic portrait of a completely fictional young scientist holding a floating bioluminescent DNA double helix between both hands. Place the subject in a dark contemporary laboratory with softly blurred glass instruments, cool blue bokeh, and clean surfaces. Keep the face, both hands, and the DNA helix sharply readable, with believable fingers and natural spacing around the hologram.
Frame the scene vertically in 4:5 with a centered triangular composition. Let the DNA helix become the brightest focal point, casting cyan and violet reflections across the subject's face, lab coat, and nearby glass. Use a soft neutral key light, a 50mm lens look at f/2.2, shallow depth of field, realistic skin and fabric texture, subtle film grain, and polished editorial detail. The expression should feel fascinated, hopeful, and quietly amazed.
The double helix must be scientifically recognizable and physically coherent. Use a completely fictional person created from scratch. No identity reference, labels, logos, readable text, watermark, extra fingers, duplicated hands, or malformed DNA.
