A real photograph in natural-light portraiture, captured with a full-frame sensor and 85mm perspective, moderate depth of field and fine low-noise texture. Headshot framing: at a school office in a tall frame: a fictional adult woman teacher in her late thirties with shoulder-length wavy brown hair in a navy blazer, head and shoulders, standing at a plain office counter signing a plain form with a pen and looking up with a friendly half-smile, an adult secretary partly visible at a desk behind, a shelf of plain binders and a window with daylight.
Light: one broad window-shaped daylight source arriving from the side, softly modelling her face and the blazer through a long light-to-shadow gradient, weak reflected daylight keeping the shadow side open, fine pores and fabric texture clearly resolved, neutral-warm midtones with gentle highlight roll-off.
Tall 9:16 portrait frame, composed vertically with the main line of the scene rising through the height of the frame. Fictional adult teachers and adult colleagues or learners only; no children or minors anywhere; fully clothed, natural realistic features, no readable text on boards, books or signs.
