Prompt
A real photograph, historical documentary genre captured on orthochromatic-style black-and-white film whose spectral response maps reds and oranges to comparatively dark greys while blues and greens lift toward luminous pale tones, smooth mid-fine silver grain, one soft directional key from the upper side giving gentle classical shading across skin and fabric planes. A night class in a wide frame: about eight adults of mixed ages seated at long wooden desks in a plain evening classroom, a woman at the front pointing to a blank blackboard while adults copy into notebooks, a tall window with dusk light behind them.
Light: one soft directional key from the upper side with gentle classical shading across faces and notebooks, reds darkened and blues lifted by the orthochromatic response, smooth silver grain, cool neutral finish; palette of silver, charcoal and pale grey; earnest, historical, focused.
Wide 16:9 frame. Fictional adults of mixed ages only, fully clothed, calm focused expressions, books and pages show blank or abstract marks only, no readable text, logos or brand names, no minors.
