奇幻场景创作指南

Production-ready prompt for DALL-E:

A low-angle, wide vista of a colossal floating city drifting above a roiling sea of stormclouds. The city is a cathedral of industry and magic: tiered basalt terraces and cantilevered brass platforms interlock like gears, with ribbed airship docks and arched aqueducts slung between districts like taut harp strings. Steam guardians—towering brass-and-iron automatons with filigreed armor plates, piston-driven limbs, exposed gear-trains, and furnace-heart cores glowing amber—patrol the sky-bridges. White jets of steam hiss from shoulder valves and knee couplings; slit-lantern eyes cut bright planes through the mist. Banners snap in the high wind; cinders spiral upward, as if the city exhales.

Lighting and mood: late golden hour, the sun crowning the city; backlit silhouettes with a halo of fire, long copper glints on polished edges, and soft bounce-light pooling under overhangs. Volumetric god rays thread torn clouds; faint ozone and oil haze texture the air. Color palette: burnished copper, oxidized teal, slate-blue and violet stormclouds, gunmetal shadows, warm amber highlights.

Foreground: a weathered stone parapet with a riveted brass telescope, rolled charts pinned by a sextant, and a small cloaked figure for scale, hair pulled by the wind. Midground: a high sky-bridge where two steam guardians cross—one kneels to examine a glowing sigil etched into the metal, steam wreathing its helm; cables, pipes, and dangling chains sway. Background: a central spire with rotating turbine rings and hovering runic monoliths; distant airships orbit like patient whales; lightning flickers in the cloud deck below.

Composition and style: strong rule-of-thirds and leading lines from parapet to bridge to spire; epic scale with crisp, intricate detail. Aesthetic: steampunk-fantasy realism—ornate yet functional engineering, no cartoon exaggeration. Medium: cinematic concept art illustration, ultra-detailed, high dynamic range, subtle film grain. Camera: 24mm wide-angle, slight upward tilt, medium depth of field to preserve scale and atmosphere. No text, no logos, no watermarks.

Generation notes:

• For a sweeping cityscape, use a wide canvas (e.g., 1792×1024).
• For a character-focused composition on a guardian, use a tall canvas (e.g., 1024×1792) and emphasize the automaton’s furnace core, pistons, and filigree.

以下为可直接用于 DALL·E 的高效提示词，围绕“雨夜书店 + 披斗篷的信使”的奇幻场景精心编写；每条均含构图、光效与质感指引。任选其一或做轻度合并微调即可。

• 方案A｜电影写实·外景广角 推荐画幅：1792×1024（横幅） 提示词： 雨夜的狭窄鹅卵石巷尽头，一家年代久远的书店在暴雨里吐出温暖的琥珀色光辉；半掩的木门微启，铜铃在风中颤响，门内旧纸与墨香被灯火烘暖成金色尘埃。披着深靛色厚呢斗篷的信使立于门外，帽檐投下阴影，只露出被雨打湿的睫毛与坚决的下颌；斗篷边缘被风掀起，像一只欲振羽翼的黑鸦。信使戴皮手套，高举一封蜡封的羊皮纸信，封印上冷蓝的符文微光在雨幕间悄然跳动；水洼映出橱窗的火光与夜色的青。石面湿亮，反射如镜；街灯的体积光将雨线拉成银丝，薄雾在书店门口打转，仿佛风暴边缘的一处港湾。橱窗深处隐约可见高耸书架、滑轨木梯与如萤的书蛾。广角低机位，三分法构图：信使占左侧三分之一，书店暖光在右侧敞开。高对比度，青蓝与琥珀的互补色分级，写实质感，浅景深，逼真的雨滴、反射与雾气。电影感、体积光、35mm镜头、微妙胶片颗粒。无可读文字的招牌，无其他路人。

• 方案B｜手绘奇幻插画·中景叙事 推荐画幅：1024×1024（方形）或 1024×1792（竖幅） 提示词： 倾盆大雨敲打老城的屋檐，一家小小的古董书店在雨夜里像一盏温柔的灯塔。门口的遮檐滴落串珠般的雨线，木框玻璃上映着晕开的金光。披斗篷的信使停步门前，斗篷内侧是暗红的绒面，外层深蓝近靛，水滴顺着衣褶汇成细流；他（她）从怀中取出一封带蜡封与黄麻绳的信，封缄上极细的符号在雨中发出像萤火般的光。书店内层层书架像林木，梯子斜靠，空气中浮着暖金的尘埃；几只发光的纸蝶绕着台灯盘旋，把雨声剪成轻软的呢喃。色彩以冷青的雨与琥珀的灯为主，点缀些许洋红反光；水彩般的晕染与可见的笔触纹理，边缘柔化，梦境气息。无可读文字，无现代车辆或霓虹广告。

• 方案C｜室内逆光·剪影氛围 推荐画幅：1024×1792（竖幅） 提示词： 从书店内部向外望去，镜头贴近窗内的雨痕玻璃：雨滴纵横成一道道轻微变形的光栅。门外，披斗篷的信使成为被门灯勾勒的剪影，斗篷在风里鼓起，像潮汐抚过海岸；举起的信在逆光里透出淡金与冷蓝交织的符文光，宛若在指间呼吸。室内近景是翻开的旧书、磨得发亮的木柜角与铜台灯的暖光晕，尘埃漂浮如金色微星；远景则是湿亮巷道与反射的路灯，一内一外叠出双重世界。浅景深，前景玻璃的水珠清晰，背景柔化；体积光穿门而入，雾气薄而可见。色调暖内冷外，高动态范围，细腻颗粒。无可读文字，无其他人物。

可选细化与控制要点（按需追加到提示词末尾）：

• 角色设定：中性面容，半遮面；斗篷材质为厚呢料与皮革搭扣；手套为深棕皮革；信封蜡封印记为抽象徽章。
• 魔法元素：微弱漂浮的符号在雨中短暂显形；发光的纸蝶或月蛾；门槛处若隐若现的圆环印记。
• 摄影与质感：低角度/仰拍；浅景深（f/1.8）；湿面反射增强；细雨与少量雾气；柔和的边缘光；轻微胶片颗粒、微光晕。
• 构图避免：不出现现代汽车、人群、霓虹文字；招牌与书封不含可读文字；不夸张卡通表情。

使用建议：

• 场景以“青蓝雨 + 琥珀灯”的冷暖对比为核心调色，能稳定强化雨夜与避风港的叙事张力。
• 若需强调信使与书店的关系，优先选择A的广角外景；若需情绪与氛围，选择C的室内逆光；故事感与童话气质则选B的插画风。
• 竖幅更适合“门与人”的垂直叙事，横幅更适合展现巷道与反射的空间层次。
