原始提示词

A vintage screen-print travel poster for a fictional tea house, portrait format. At the top, a large bold serif headline in English reading exactly "LANTERN TEA HOUSE". Directly beneath it, a Chinese title in brush calligraphy reading exactly "灯笼茶馆". In the centre, a flat illustration of a glowing red paper lantern with no writing on it, hanging above a steaming clay teapot and two small cups, under a deep indigo night sky with a single crescent moon and a few stars, with saffron and cream accents and a subtle paper grain. At the bottom, two lines of small, clean sans-serif text: the first reading exactly "Open nightly from 8 PM to 2 AM" and the second reading exactly "每晚八点至凌晨两点营业". These four lines are the only text on the poster, with no signs, labels or characters anywhere else. All lettering crisp, correctly spelled and fully legible, generous margins.

原始提示词

A backlit portrait of a woman in her early thirties standing in a meadow of tall grass at golden hour. The low sun behind her creates a bright rim light that outlines her loose auburn hair, her shoulders and the edge of her cream linen shirt. Her face is softly lit by warm bounce light, with natural skin texture and light freckles, a calm expression, looking just past the camera. Warm haze, a gentle lens flare, creamy background bokeh. An original, non-famous person. Photorealistic, 85mm lens at f/1.8, shallow depth of field.

A studio product photograph of a pour-over coffee set on a pale oak tabletop: a matte speckled stoneware dripper with visible glaze pinholes, a clear borosilicate glass carafe half full of amber coffee, a gooseneck kettle in brushed copper with fine circular grain and a soft reflection of the window, and a small walnut tray with crisp wood grain. Soft diffused window light from the left, gentle shadows, a light linen backdrop. Faithful material rendering: the ceramic, glass, metal and wood each look exactly like themselves. No logos, no text, no brand marks. Photorealistic, 100mm macro lens at f/8.

原始提示词

An ultra-wide 21:9 landscape panorama of a glacier-carved mountain valley at sunrise. Jagged granite peaks dusted with fresh snow catch pink and gold first light, and low clouds cling to the ridgelines. A turquoise braided river winds across a wide valley floor of golden grass and dark boulders, and a single small wooden cabin with a thin line of chimney smoke gives a sense of scale. Crisp detail from the frosted grasses in the foreground to the distant summits. Landscape photography, natural colours, deep focus.
