文生图创作示例

提示词

Create a square retro mid-century travel poster for the fictional coastal city "PORT AMBER". Feature a single art-deco cliffside observatory tower, stepped terraces, small surrounding rooftops, a curving coastal road, and a simplified harbor seen from a slightly isometric aerial view. Use minimalist screen-printed travel-poster language: precise black technical linework, fine cross-hatching, visible silkscreen grain. Strict 1:1 square composition, observatory centered below the title, disciplined border margins. Use exactly three colors only: warm cream paper, black linework, and flat vermilion red; fill the upper sky behind the title in solid vermilion. Render "PORT AMBER" once in bold cream sans-serif at the top. No other text, logos, people, cars, watermark, gradients, or photorealism.

提示词

Create a single, polished square 1:1 luxury fashion campaign key visual for a fictional contemporary label named RASA. One young adult model wears a sharply tailored charcoal suit, a crisp white ribbed top, and one long chartreuse silk scarf, holding a small matte-black geometric clutch. Set the model in a clean sculptural studio of curved cobalt-blue walls and one smooth pale-gray plinth, with a glossy but restrained floor reflection. Use high-end contemporary fashion photography, impeccable art direction, premium materials, and a clean commercial finish. Keep one model centered with balanced architectural negative space, a low eye-level camera, broad softbox lighting, and a narrow warm sun strip on one wall. Use cobalt blue, charcoal, ivory, chartreuse, and subtle chrome highlights. No torn paper, distressed texture, film grain, printed ephemera, grid, extra people, visible brand name, text, logo, or watermark.

提示词

Create a square automotive design specification board for a fictional 1980s-inspired compact station wagon called "NORTHLINE K-19". Use warm bone-white satin paint, satin-black lower cladding, a boxy silhouette, low air-suspension stance, wide riveted fender flares, black deep-dish wheels, thin rectangular headlights, black front splitter, and one asymmetric X-pattern headlight cover. Use crisp realistic 3D automotive render lighting and a restrained Swiss industrial-design layout. Strict 1:1 square; exactly four views in a 2x2 grid—front three-quarter, side profile, rear three-quarter, and detail close-up—plus small material, wheel-fitment, and silhouette panels. Render "NORTHLINE K-19" and "CONCEPT STUDY" once each in clean black sans-serif. No real logos, people, busy background, or watermark.

Create a premium landscape 16:9 studio photograph of a fictional compact digital camera called "MICA-01": translucent smoke-gray polycarbonate body, circular brushed-aluminum lens bezel, tiny amber status light, woven charcoal wrist strap, and one tactile top dial. Place it slightly left of center on an off-white plinth against a pale warm-gray seamless background, at a gentle front three-quarter angle, with generous clean negative space on the right. Use crisp industrial-design product photography, realistic material rendering, soft diffused daylight, and controlled shadow. No readable logo, extra text, hands, people, or watermark. Preserve exact silhouette, material, and placement for a later edit.

Transform the uploaded MICA-01 camera photograph into a premium landscape 16:9 desktop e-commerce product-detail page. Keep unchanged: exact camera silhouette, translucent smoke-gray body, brushed-aluminum lens bezel, amber status light, woven strap, proportions, front three-quarter view, and material realism. Add a refined top navigation, narrow left thumbnail gallery, right information panel with "MICA-01", "$280", three color swatches, quantity control, and black "ADD TO BAG" button; add a lower strip with four feature icons and neutral technical cards. Keep the camera, lens, amber light, strap, product name, price, and primary button unobstructed. Authentic high-end conversion-focused desktop retail page, with precise spacing, elegant sans-serif typography, thin dividers, and no external logos or watermark.

原图 (提示词)

Create a complete, visually rich landscape 16:9 fashion editorial photograph of a young woman with short dark wavy hair and slim clear glasses descending a monumental cobalt-blue tiled stairway in an outdoor modernist courtyard. She wears a structured ivory sleeveless vest over a black ribbed top, wide-leg charcoal trousers, black leather loafers, and carries a polished silver shoulder bag. The scene includes a brushed-steel handrail, a coral-red plaster wall, a large cream canvas parasol, three mature green potted plants, and pale stone paving. Use high-end fashion photography with hard warm late-afternoon sun, cobalt and coral shadows, and sharp architectural lines. Preserve the subject, stair geometry, coral wall, parasol, rail, plants, palette, and light-shadow pattern for the later edit. No text, logos, watermark, or other people.

Transform the uploaded photograph into a refined contemporary 16:9 fashion illustration. Keep unchanged: the woman's face, hair, glasses, ivory vest, black top, charcoal trousers, loafers, silver bag, descending pose, cobalt tiled staircase, coral-red wall, cream parasol, brushed-steel rail, three green potted plants, late-afternoon light direction, and full composition. Render the scene with sophisticated opaque gouache color fields, colored-pencil contour work, and restrained screen-print texture accents. Keep the face, glasses, bag, full body silhouette, staircase geometry, rail, parasol, plants, and long shadow paths unobstructed. The result should feel like an art-directed contemporary fashion-magazine illustration: vibrant, spatially rich, and polished; no text, logo, watermark, added people, blank white background, paper tears, or grunge texture.
