官方六大模板详解
以下模板源自 Google AI 官方教程，可直接复制使用，高效生成专业级 AI 图像。
一、逼真摄影
A photorealistic [shot type] of [subject], [action/expression], set in [environment].
The scene is illuminated by [lighting], creating a [mood] atmosphere. Captured with a
[camera/lens], emphasizing [details]. [Aspect ratio].技巧：避免将 [shot type] 与 [subject] 直接并列堆叠，否则 AI 难以准确解析画面层次。
实例：
A photorealistic close‑up portrait of an elderly Japanese potter, hands covered in wet clay, inside a sun‑drenched studio…
二、风格贴纸
A [style] sticker of a [subject], featuring [key characteristics] and a [color palette].
The design has [line style] and [shading style]. Background white.技巧：添加白色背景可大幅降低后期抠图成本；若需透明 PNG 格式，请将指令改为 Background transparent。
实例：
kawaii‑style sticker of a red panda wearing a bamboo hat, munching lea ves…
三、文字精准
Create a [image type] for [brand] with the text "[Text]" in a [font style].
Design is [style], with a [color scheme].技巧：务必在提示词中明确指定字体，否则 AI 可能生成难以辨认的怪异手写体。
实例：
Create a 4K promotional poster for YutoGPT with the text "Intelligence Beyond Limits" in a sleek modern sans-serif font (e.g., Helvetica Neue UltraLight). Design is minimalist and futuristic, with a black–white–platinum color scheme, accented by subtle gradients and metallic highlights.
四、商业产品照
A high‑resolution, studio‑lit product photograph of a [product] on a [surface].
Lighting: [setup] to [purpose]. Camera angle: [angle] showcasing [feature].
Ultra‑realistic, sharp focus on [detail]. [Aspect ratio].技巧：清晰定义 [angle]（拍摄角度）。若不指定，模型默认采用 30° 俯视视角，可能导致电商主图比例失衡，缺乏专业质感。
实例：
A high‑resolution, studio‑lit product photograph of a polished stainless‑steel wristwatch on a black glossy marble surface.
Lighting: a three‑point setup with a large softbox key light to highlight the reflective metal, rim light to define edges, and a low‑intensity fill light to eliminate harsh shadows, achieving a premium editorial look. Camera angle: a 45‑degree close‑up shot showcasing the watch face and intricate detailing of the bezel. Ultra‑realistic, razor‑sharp focus on the engra ved numerals and sapphire crystal clarity, with soft background fall‑off to emphasize luxury. 1:1 aspect ratio.
五、极简留白
A minimalist composition featuring a single [subject] positioned in the [corner].
Background: vast [color] canvas, creating negative space. Soft subtle lighting.
[Aspect ratio].技巧：将主体置于左上角，便于后期叠加电商标语，设计师可快速提取主视觉（KV）元素。
实例：
A minimalist composition featuring a single sculptural chair positioned in the lower right corner. Background: vast ivory‑white canvas, creating expansive negative space. Soft, subtle diffused lighting with gentle gradients across the backdrop. Aspect ratio: 1:1.
六、漫画分格
A single comic book panel in a [art style]. Foreground: [character + action].
Background: [setting]. Caption: "[Text]". Lighting creates a [mood] mood.
[Aspect ratio].技巧：将 Caption（对白）直接交由模型渲染，实现图文一体化输出，免去后期排版工序。
实例：
A single comic book panel in a vintage American comic book art style. Foreground: a young hero in a red jacket leaping forward, fist raised, mid‑punch toward an off‑panel villain. Background: a crumbling city street with shattered windows and smoke rising from buildings. Caption: “This city still has hope—as long as I stand!” Lighting creates a dramatic, high‑contrast mood. Aspect ratio: 1:1.
五条大神级提示词秘技
掌握这些方法，你写的提示词将更有层次、更完整、更可控。
- 一、分步构建：按背景→主体→光线的顺序依次描述。AI 的推理路径更清晰，生成结果更精准。
- 二、正向语义引导：与其使用 "no cars" 等否定表述，不如用 "an empty cobblestone street at dawn" 进行正向场景描述，效果远优于直接禁止。
- 三、专业镜头语言：运用 macro shot、low‑angle、tilt‑shift 等摄影术语，可精准锁定画面视角与构图。
- 四、具象细节词汇：比如
visible linen wea ve（肉眼可见的亚麻织纹），此类细节描述能显著提升材质质感表现，避免纹理模糊。 - 五、迭代式微调：通过指令
Keep everything else, turn sunset warmer，可精准调整特定元素，而不扰动已满意的画面部分。
实战案例：用五大秘技写一个完整提示词
Step 1: 背景
An empty cobblestone street at dawn, faint mist curling along the ground, rows of weathered stone buildings with shuttered windows. No modern cars, no neon lights.
Step 2: 主体
Foreground: a young swordsman in a tattered cloak, kneeling with one hand gripping the sword stuck into the ground. His visible linen wea ve tunic catches the morning breeze. Expression fierce yet determined.
Step 3: 光线
Lighting creates a dramatic, high-contrast mood: warm sunrise glow breaking through fog, casting long shadows across the street.
Camera & Composition
Low-angle macro shot with a subtle tilt-shift effect, emphasizing the hero's silhouette and the texture of the cobblestones.
Caption
"This is where my journey begins."

Q1：我已采用叙事句式，为何生成效果仍不理想？
请检查叙事句是否过于冗长或笼统。理想长度为 3-5 句，需包含一个核心动作、一个主要环境、一种特色光线。句子过长，AI 可能遗漏关键信息。
Q2：如何在文字模板中正确处理字体设置？
务必在 [font style] 位置明确指定字体名称（如 Helvetica Neue UltraLight）。否则 AI 可能自动选用不美观的手写体。
Q3：生成图像中频繁出现不想要的元素，该如何处理？
避免使用负面词汇（如 no cars），改用语义描述正向引导画面（如 an empty cobblestone street）。同时可尝试"分步构建"法，先确定背景，再逐步添加主体与光线。
