FLUX 3 Klein プロンプトの書き方

1. 1. 最初に主な被写体、次に場面を書きます。冒頭の言葉がフレームの中身を名指ししていると、静止画は誘導しやすくなります。
2. 2. 照明、構図、そしてカメラやレンズの見え方を足します。たとえば 85mm の商品フレーム、50mm のポートレート、広角 24mm の室内です。
3. 3. 画像に出したい言葉は二重引用符で囲み、絵に合うアスペクト比を指定します。たとえば 1:1、4:5、16:9、9:16 です。
4. 4. FLUX 3 Image にネガティブプロンプトはありません。省きたいものを並べるのではなく、素材、光、色を含めて、画面にあるべきものを書いてください。

• スタジオ商品写真

  A matte sage-green ceramic pour-over kettle stands in three-quarter view on a seamless warm-gray studio sweep, handle to the left and spout angled slightly toward the camera. A large overhead softbox wraps the curved body, a thin cool rim light traces the right edge, and a soft contact shadow anchors the base.

• EC のフラットレイ

  An overhead flat lay of a linen skincare set on pale oak: a frosted pump bottle, a squat glass cream jar, a folded oatmeal washcloth, and three dried eucalyptus stems spaced with even gaps. Soft daylight from the upper left throws short, even shadows, and every item stays sharp from edge to edge. 50mm top-down frame with a generous margin so each piece can be cropped into a catalog tile. Clean e-commerce photography, airy and orderly. Palette of oat #E7E1D6, sage leaf #A8B5A2, frosted white, and a cork lid #C9A27A. The jar lid is stamped "DAILY CLOUD". Aspect ratio 1:1.

• 自然光のポートレート

  A woman in her early thirties with a short black bob and a rust linen shirt sits beside a tall window, looking just past the lens with a calm, closed-mouth expression. Late-afternoon sun from camera left lays a warm band across her cheek and the plaster wall, while the rest of the room rests in open shade. Medium close-up on a 50mm lens at f/2.8, eyes sharp and the window frame gently soft. Natural-light portrait, realistic and quiet. Colors of rust #C4622D, warm skin, and a cool gray wall #D5D8DE. Aspect ratio 4:5.

• シネマティックな 21:9 の風景

  A lone red fishing hut stands on black volcanic sand where a pale river meets a steel-blue sea, with low clouds stacked along the horizon at blue hour. One warm window glows against the cool air, and the wet sand mirrors the sky in a long ribbon toward the foreground stones. Wide 24mm landscape frame, horizon on the lower third, deep focus from the near pebbles to the distant headland. Cinematic still, quiet and large in scale. Palette of steel blue #4C6A86, ember orange #E07A3D, and charcoal sand #2A2A2C. Aspect ratio 21:9.

• フードフォト

  A thick slice of olive-oil lemon cake rests on a speckled stone plate, one corner broken open so the tender crumb shows, with a thin glaze catching the light and a few curls of zest beside it. Soft side-window light, slightly warm, leaves a small shadow under the plate. 90mm macro at a wide aperture, the glaze sharp and the far rim of the plate falling soft. Tight three-quarter food frame, plate filling the lower half. Editorial food photography, appetizing and precise. Colors of lemon #F2D15A, olive crumb #C9B48A, and stone gray #B7B2AA. Aspect ratio 3:2.

Bold condensed lettering stacked near the top reads "NIGHT MARKET", and a smaller line directly under it reads "FRIDAY 9 PM". The letters are crisp, high contrast, and fully inside the frame with clear space around each word. Flat graphic poster with a light paper grain, centered and symmetrical.

• ロゴとアイコンのコンセプト

  A simple app icon of a single folded paper crane, centered on a rounded square and built from two flat shapes plus one thin highlight along the wing. Even frontal light, generous padding on every side, and a straight-on orthographic view so the mark stays clear at a small size. Crisp vector edges, flat color, and a calm geometric style. The crane is porcelain white on a deep teal field #0E6E6A, with a small gold beak #E0B15C. The icon is the crane alone, ready to sit on a home screen. Aspect ratio 1:1.

• アイソメトリックイラスト

  An isometric cutaway of a tiny neighborhood bakery on a clean cream ground: a glass counter stacked with loaves, a wood oven with a warm glowing mouth, and a bicycle parked at the curb. Soft even light across the scene, with a small orange glow from the oven and every edge aligned to one isometric grid. Three-quarter isometric illustration, tidy and toy-like, outlined shapes filled with flat color. Palette of cream #F6F1E7, brick red #C4554A, butter yellow #F0C95A, and a sage awning #7E9A78. The awning lettering reads "BAKE". Aspect ratio 1:1.

• アニメ調のキャラクター

  A teenage anime courier with a cobalt bob and a sunflower-yellow jacket stands on a rainy crosswalk, one hand raised in a small wave and a messenger bag across the chest. Overcast daylight, soft reflections on the wet asphalt, and city signs softened in the background. Full-body framing from a slight low angle, clean line art, cel shading, and a few glossy highlights on the jacket. Bright anime still, energetic and easy to read at a glance. Colors of cobalt #2F5FA8, sunflower #F2C14E, and rain gray #8E97A3. Aspect ratio 2:3.

• 建築インテリア

  A sunlit reading room in a concrete house, seen from the doorway: a long oak table, two linen chairs, and a floor-to-ceiling window opening onto pines. Morning light rakes across the tabletop from the left, revealing the wood grain and laying soft mullion shadows on the floor. 24mm architectural photograph, verticals kept straight, deep focus from the near chair to the glass. Calm and precise interior, palette of warm oak #C49A6C, cool concrete #C9C7C2, and pine green beyond the window. Aspect ratio 3:2.

  A clean infographic card that explains brewing tea in three left-to-right panels: a kettle, a timer showing four minutes, and a filled cup, each panel numbered and separated by a thin divider. Wide margins, a simple grid, and a short heading at the top that reads "BREW IN THREE". Flat vector layout with even illumination and crisp alignment. Palette of paper white, ink #1C1C1C, and a single teal accent #1F8A84. The panel labels read "HEAT", "WAIT", and "POUR" in that order. Aspect ratio 16:9.

• ファッションエディトリアル

  A model in a structured ivory coat walks through a pale stone colonnade, coat hem caught mid-step, one hand in a pocket, gaze directed down the hall. Hard noon sun cuts bright bars of light between the columns, with deep cool shade in the intervals. Full-length fashion frame on an 85mm lens, the figure placed on the left third and the columns repeating into the distance. Editorial fashion still, crisp and architectural. Colors of ivory #F4F0E6, stone #D9D3C7, and a narrow black belt #1A1A1A. Aspect ratio 9:16.
