Midjourney 或者說 AI Generative Art 應該是2022年藝術界比較大的事情。我覺得這種工具對普羅大眾最大的意義，在於對藝術描寫的學習與認識，透過不同的 prompt，效果馬上可以看見，這真的不是傳統藝術教育容易達到的。
我以下用白衣大士（請合十）來練習不同 Prompt 的效果。我也不是什麼專家，就是練習而已，覺得好玩。
首先，我要有一尊白衣大士：
A beautiful girl wearing a white cloak and riding a flying Chinese Dragon
白衣大士背後怎麼可以沒有月亮？
A beautiful girl wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon
到目前為止都有點童趣，所以我要一點仙氣：
A beautiful girl wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon, swirl smoke
再來就是構圖的調整，我覺得 Cinematic Composition 很好用
A beautiful girl wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon, swirl smoke, cinematic composition
大概這樣子，可以開始加上水墨風格了
A beautiful girl wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon, swirl smoke, cinematic composition, Chinese ink painting
加上背景，不過我覺得不是很明顯
A beautiful girl wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon, swirl smoke, cinematic composition, Chinese ink painting, epic detailed cinematic background
幫她加點量體：

因為白衣大士通常都是直幅的，所以修改一下，另外加上會增添寶氣的東西
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon, swirl smoke, cinematic composition, Chinese ink painting, epic detailed cinematic background, glow crystal, --aspect 9:16
打光很重要，Midjourney 中有很多打光的效果，我這次先用戲劇效果光：
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon, swirl smoke, cinematic composition, Chinese ink painting, epic detailed cinematic background, glow crystal, dramatic lighting, --aspect 9:16
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon, atmospheric, white swirling smoke::3, white floating smoke, cinematic composition, Chinese ink painting::3, epic detailed cinematic background, glow crystal, dramatic lighting, --aspect 9:16
嘗試看看補一點效果，我增加了極光，並且把時間調成晚上
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon, big Decorative full moon, atmospheric, white swirling smoke::3, white floating smoke, cinematic composition, Chinese ink painting::3, epic detailed cinematic background, glow crystal, dramatic lighting, Aurora, Evening, --aspect 9:16
月亮太白了，改成黃色的
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon::3, big yellow Decorative full moon::2, atmospheric, white swirling smoke::3, white floating smoke, cinematic composition, Chinese ink painting::3, epic detailed cinematic background, glow crystal, dramatic lighting, --aspect 9:16
除了仙氣，還要金光祥雲
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon::3, big yellow Decorative full moon::2, atmospheric, white swirling smoke::3, white floating smoke, golden auspicious clouds, cinematic composition, Chinese ink painting::3, epic detailed cinematic background, glow crystal, dramatic lighting, --aspect 9:16
加上蓮花的意象。在 Midjourney 添加東西越來越多的時候，有些就會融合到其他物件當中
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon::3, big yellow Decorative full moon::2, atmospheric, white swirling smoke::3, white floating smoke, golden auspicious clouds, cinematic composition, Chinese ink painting::3, floating lotus flower, epic detailed cinematic background, glow crystal, dramatic lighting, --aspect 9:16
再做點微調，主要是把顏色調整一下，然後時間移到日出
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon::3, big yellow Decorative full moon::2, atmospheric, white swirling smoke::2, white floating smoke, golden auspicious clouds::2, cinematic composition, Chinese ink painting::3, floating lotus flower, epic detailed cinematic background, glow crystal, dramatic lighting, sunrise, muted colors, --aspect 9:16
Midjourney 還可以輕易的加上甚至疊加已經存在的風格，例如最流行的 Craig Mullins
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon::3, big yellow Decorative full moon::2, atmospheric, white swirling smoke::2, white floating smoke, golden auspicious clouds::2, cinematic composition, Chinese ink painting::3, floating lotus flower, epic detailed cinematic background, glow crystal, dramatic lighting, sunrise, muted colors, by Craig Mullins, --aspect 9:16
換個畫師試試看
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon::3, big yellow Decorative full moon::2, atmospheric, white swirling smoke::2, white floating smoke, golden auspicious clouds::2, cinematic composition, Chinese ink painting::3, floating lotus flower, epic detailed cinematic background, glow crystal, dramatic lighting, sunrise, muted colors, by Alex Flores, --aspect 9:16
Craig Mullins 風格的有點太突出了，所以再把顏色調比較黑白一點，並且強化水墨參數：
A beautiful girl with curvy body wearing a white cloak and riding a flying Chinese Dragon::3, big yellow Decorative full moon::2, atmospheric, white swirling smoke::2, white floating smoke, golden auspicious clouds::2, cinematic composition, Chinese ink painting::4, floating lotus flower, epic detailed cinematic background, glow crystal, dramatic lighting, sunrise, muted colors, black and white, by Craig Mullins, --aspect 9:16
看起來左下角的還可以？打算變成結緣 NFT 了（特大誤），可以請 Midjourney 多畫幾個看看。（甲方：「這個風格不錯，你多畫幾組讓我挑！」）說到 NFT，Midjourney 目前的合約是要分紅的，如果你真的拿了作品去發行， Midjourney 說月收入 2 萬美金以上，要求分潤20%。
我覺得左上好像可以拿去結緣（誤），就出大圖吧。如果你都沒有使用過 Midjourney，相信你大概可以知道這個繪製的過程，實際上就跟你學藝術賞析與評論很像，你要能夠說出主題、構圖、光影、質地、時代、風格、氣氛等等，然後再用這些話語當成指令給 AI 去再生，就是一個解構與再結構的過程。對於非設計師或非藝術家而言，我覺得這個過程與意義比「取代設計師」還重要。
