A man in a perfectly weighted navy wool blazer — subtle texture, unstructured but precise — over a pale blue striped cotton Oxford shirt, open collar, no tie. Dark charcoal slim trousers with a clean break at the ankle. Brown suede Chelsea boots. A simple brown leather strap watch. Reading glasses in the breast pocket. One hand holding an old hardcover book. Expression: looked up from reading just now, slightly surprised to be seen.
Close mid shot — chest and face filling the frame. Seated at a dark wooden desk in a private library. Bookshelves floor to ceiling behind him, softly out of focus. Camera at eye level, intimate distance. Single warm desk lamp to his right — warm amber pool of light on his face, the open book, the blazer's texture. Rest of the dark wood library in deep warm shadow. The light of a man who reads after dinner.
