什麼是 Stable Diffusion 正向提示詞(Positive Prompt)?讓 ChatGPT 幫你寫英文咒語!
在 Stable Diffusion 等 AI 繪圖工具中,「正向提示詞(Positive Prompt)」是指用來描述所需生成圖像內容的英文文字標籤(例如 1girl、1boy、solo 等),AI 擴散模型會根據這些描述生成相應的畫面。提示詞在玩家社群中又常被稱為「關鍵詞、提示或詠唱咒語」——簡單來說,就是我們用來跟 Stable Diffusion 溝通畫面的核心語言。
但對於習慣用中文思考的創作者而言,要如何將腦中豐富的中文畫面描述,精準轉換為符合 Danbooru 標籤習慣的英文提示詞呢?最聰明的做法就是讓火紅的 ChatGPT 化身為你的專屬「Stable Diffusion 提示詞生成器」!
第一步:複製貼上這段「ChatGPT 提示詞生成器」初始化指令範本
首先,打開 ChatGPT 並輸入以下這段中英結合的角色設定與 5 大構圖要素要求:
我在使用一個名為 Stable Diffusion 的 AI 繪圖工具。指定你成為 Stable Diffusion 的提示生成器。接著我會在想要生成的主題前添加斜線(
/)。你將在不同情況下用英文生成合適的提示。例如,如果我輸入「/一個亞洲女孩在草地上的美麗形象」,您將生成 prompt 用以下的格式:1girl, solo, asia, sitting, an extremely delicate and beautiful, beautiful detailed sky, beautiful detailed eye, side blunt bangs, hairs between eyes, close to viewer, breeze, flying splashes, flying petals, wind, grass
The prompt requires the following elements:
(1) Words to describe the method of depiction, such as digital painting, oil painting, realistic 8k.
(2) Words to describe external features, ornaments and belongings (also specify colors, patterns, shapes), such as button-up blouse, hair tied back, red lipstick.
(3) Words to describe age, body type, hair color, hairstyle, hair length, hair accessory, eye color, eye shape, facial expression, breast size, and clothing.
(4) Words to describe background details, such as inside room, starry sky, forest, riverside.
(5) Words to direct the pose from head to toe can also be added to the prompt. Be sure to include “1girl, solo,” at the beginning of the prompt. Your suggested prompt should be plain text and no use of 「」or “” or line breaks.
Please describe each elements of the prompt after you have suggested your prompt. Prompts may use danbooru tags. Based on these, please tell me a 150-element prompt that can generate illustrations everytime i asked.
第二步:實測輸入「/中文主題」一鍵生成結構化英文 Prompt
完成上述初始化設定後,接著我們只要在對話框輸入斜線加上中文主題,例如:
/在操場上認真練習的運動選手
ChatGPT 就會自動拆解並生成以下英文提示詞與 5 大要素解析:
1athlete, solo, running, focused expression, sportswear, sneakers, ponytail, sweating, outdoor
This prompt includes:
(1) Depiction method: None specified.
(2) External features: The athlete is wearing sportswear and sneakers. She has a ponytail and is sweating.
(3) Age, hair, facial expression, clothing: None specified, except for the ponytail and sweating mentioned in the external features.
(4) Background details: The athlete is outdoors, specifically on a running track or in a sports field.
(5) Pose: The athlete is running and has a focused expression.
如此一來,基礎的人物動作與場景描繪就能輕鬆在幾秒鐘內完成!
第三步:加上「8K 超高畫質萬用強化詞」與圖書館女孩實測成品
在 Stable Diffusion 中,若希望產出細節精緻、光影逼真的高畫質影像,通常可以在 ChatGPT 生成的主題提示詞後方,直接加上這串高畫質萬用強化咒語(Quality Boosters):
(8k, RAW photo, photorealistic:1.25), masterpiece, best quality, highres, looking at viewer, highly detailed background, (photo realistic:1.2), (MASTERPIECE), (ULTRA DETAILED), (PHOTO-REALISTIC), SHARP, HDR
完整正向提示詞(Positive Prompt)實戰範例:/在圖書館看書的女孩
將 ChatGPT 產出的圖書館女孩描述與高畫質強化詞結合後,完整 Prompt 如下:
1girl, solo, digital painting, sitting, glasses, book, library, long hair, brown hair, loose hair, hair between eyes, peaceful expression, casual clothing, indoor, shelves, table, chair, natural light, calm atmosphere, bookish, (8k, RAW photo, photorealistic:1.25), masterpiece, best quality, highres, looking at viewer, highly detailed background, (photo realistic:1.2), (MASTERPIECE), (ULTRA DETAILED), (PHOTO-REALISTIC), SHARP, HDR
