AI でどう作る?
STEP 1
粒なしのきれいな画で出す
clean・no grain と書く
AI への指示Film grain source: a clean, noise-free static medium shot; smooth gradients on the wall and in the shadows.
Film grain source: a clean, noise-free static medium shot; smooth gradients on the wall and in the shadows. Character: the woman from the character reference sheet: same face, mole near the right cheekbone, shoulder-length straight black hair tucked behind the left ear, plain oatmeal-beige wool crew-neck sweater, dark indigo jeans, white plain sneakers. Location: a small Japanese apartment room with a light wooden floor, a low table and a window with sheer white curtains. 0.0s-2.0s: she sits by the window holding a mug, looking out. 2.0s-3.5s: she takes a sip. 3.5s-5.0s: she lowers the mug and rests her head against the wall. 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, plaster wall, ceramic mug, wool knit. Natural, neutral color, no heavy grading. No text, no logos. Ambient sound: quiet room tone, a distant train.
