Professor Leaning Against Worn Chalkboard

Cinematic medium shot from a slight low-angle perspective. [A thoughtful man] leans back against a surface in a three-quarter profile view, gazing thoughtfully off-camera. He is wearing [a rumpled white button-up shirt with rolled-up sleeves, a loosely knotted dark textured necktie, and brown chino pants]. Behind him is an expansive, weathered black chalkboard densely covered in white chalk notes, diagrams, arrows, and philosophical formulas. The scene is illuminated by soft, diffused medium-key lighting from the right, creating gentle, open shadows while preserving delicate mid-tone details in the clothing and skin. Color grading is warm, desaturated sepia with a subtle greenish-yellow tint reminiscent of aged film stock under fluorescent lighting, featuring slightly lifted blacks and organic 50mm film grain.
