GPT x MJ 夢幻聯(lián)動玩法

場景:訓(xùn)練 GPT 提詞器人設(shè),生成 Midjourney 的繪圖語句,實(shí)現(xiàn) AI 聯(lián)動繪圖。
用 GTP 訓(xùn)練自己的 MJ 提詞器進(jìn)行施法,是一種便捷的出圖手段,但是在沒有精細(xì)化約束 prompt 語法的情況下,輸出的咒語通常夾雜「噪音信息」,需要針對性修正后根據(jù)自己的目標(biāo)來調(diào)整畫面,以下是一個(gè)完整的使用實(shí)例:
本文使用了訓(xùn)練好的 GPT 人設(shè),篇幅關(guān)系,不贅述訓(xùn)練過程,重點(diǎn)看拿到 prompt 之后怎么用。
??? Step 1、GTP 提詞:
IDEA:想要畫一個(gè)《天空之城》

原始提詞:
A magical floating city high above the clouds, with tall buildings that intertwine with vines and trees on the cliffs. The city is surrounded by an endless sea of clouds, occasionally flashing with lightning and showering rain. The sounds of children's voices and birdsong echo throughout the city, making it feel like a heavenly world. Photorealistic style, progressive composition, shot on 35mm, medium shot, warm colors, cinematic lighting, —ar 16:9
??? Step 2、問題修正:
1.? occasionally flashing with lightning and showering rain:畫面要素過多,去掉。
2.? The sounds of children's voices and birdsong echo throughout the city:無法形成畫面,去掉,或留飛鳥。
3.? making it feel like a heavenly world:僅 heavenly 為有效詞匯,用更明確的 rising light (圣光)來塑造這種環(huán)境氛圍。
咒語修正:
A magical floating city high above the clouds, with tall buildings that intertwine with vines and trees on the cliffs, the city is surrounded by an endless sea of clouds, cinematic lighting, rising light, progressive composition, 35mm, medium shot, warm colors, photorealistic, —ar 16:9
?? Step 3、注入想法:
開闊的視野,漫畫風(fēng)格:
1.? 用 anime style 替換 cinematic lighting 和 photorealistic,因?yàn)楹髢烧邔憣?shí);
2.? 視野調(diào)整為開闊的 expansive view;
3.? 去掉可能出現(xiàn)的電線和路人 --no powerlines human;
4.? 加個(gè)美感 buff——esthetic;
正式咒語:
Anime style, a magical floating city high above the clouds, with tall buildings that intertwine with vines and trees on the cliffs, the city is surrounded by an endless sea of clouds, warm colors, rising light, progressive composition, expansive view, esthetic —ar 16:9 --no powerlines human
MJ 跑圖:

結(jié)束了嗎?
游戲才剛開始。
玩起來:
1.? 加點(diǎn)瀑布,強(qiáng)化視覺落差和力量感——waterfall;
2.? 補(bǔ)充輪廓光強(qiáng)化氛圍和體積感——rim light;
3.? 畫面有點(diǎn)膩,把暖色調(diào)整為舒適軟光—— cozy light;

戳一張:
還不錯的樣子,一切盡在掌控。

按此套路「突突突」即可。
??更多實(shí)例:
例 1: 將視角扭到鳥瞰透視 aerial perspective:

例 2: 加移軸 tilt-shift 營造小人國的觀感:

例 3: 寫實(shí)等軸微縮模型 isometric diorama landscape:

?? 享受創(chuàng)造的樂趣:
更多時(shí)候,可以利用 GPT 善于聯(lián)想和補(bǔ)充細(xì)節(jié)的優(yōu)勢來放大畫面的觀賞性,不照搬它提供的參考。
或者...確實(shí)想偷懶(打臉),現(xiàn)在就可以開始使用 GPT 馴養(yǎng)一個(gè)優(yōu)秀的永動機(jī)小助理。
Have fun.
