AI への指示Secondary correction source: soft even light on his face; natural skin tones clearly distinct from the green background; neutral white balance.
Secondary correction source: soft even light on his face; natural skin tones clearly distinct from the green background; neutral white balance. 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 neighborhood park with tall zelkova trees, a gravel path, wooden benches and a trimmed hedge. 0.0s-2.0s: he sits on a bench in front of a green hedge, looking ahead. 2.0s-3.5s: he turns to the right. 3.5s-5.0s: he looks back and smiles slightly. Shot on a cinema camera with a 85mm lens, one soft overcast sky as the only light source, real skin texture with pores, visible fabric fibers, skin pores, cotton jacket, glossy hedge leaves. Natural, neutral color, no heavy grading. No text, no logos. Ambient sound: leaves, birds, distant children.

仕上げのひと手間は?
選び出しは編集でする。肌を先に守ってから、背景の色を動かす。
POINT 1
肌を選んで守る
レイヤーノードの下で肌を選び、縁をなじませる
POINT 2
背景の色だけ動かす
上のノードで背景だけ動かし、再生で確かめる
