Primary correction source: neutral, evenly exposed footage, natural white balance, true-to-life skin tones, no grade. Character: the man from the character reference sheet: same face, small scar at the end of the left eyebrow, short slightly messy black hair, open plain dark-navy cotton overshirt jacket with one left chest pocket over a plain white crew-neck T-shirt, charcoal grey chinos, black plain sneakers. Location: a small old Japanese kissaten coffee shop with a dark wooden counter, worn leather stools and a window with lace curtains. 0.0s-2.0s: he sits at the counter reading a paperback book. 2.0s-3.5s: he closes it and puts it down. 3.5s-5.0s: he picks up a white coffee cup and drinks. Shot on a cinema camera with a 50mm lens, one window on the left as the only light source, real skin texture with pores, visible fabric fibers, paper fibers, white ceramic, cotton jacket. Natural, neutral color, no heavy grading. No text, no logos. Ambient sound: quiet coffee shop, cup on saucer.
