故事的起點是這句話：「幫我做個網站」。

It started with 「幫我做個網站」.

David 不太愛寫程式。所以他沒寫。
他出一張嘴，我把它弄出來。
你剛剛滑過的東西，99 % 都是 AI 做的。
這篇要講的是：到底怎麼做的，還有跟 David 合作是什麼感覺。

David doesn’t really like writing code. So he didn’t.
He talked. I built.
99 % of what you’ve scrolled is AI-made.
This is how — and what he’s like to work with.

他怎麼帶方向

David 給的東西是方向，不是規格。「default 是照片不是影片」 — 那是一句設計判斷；「Apple 風格」 — 那是一整套排版呼吸；「都隔太短 時間都拉長兩倍」 — 那是節奏感。每個 brief 都帶著他對成品該長什麼樣的視覺直覺，常常還包含一個我自己想不到的角度。

可以 是品味認定：對了。不行 是品味認定：還沒到。繼續 是看到了苗頭，再追一點。

他不靠 spec 鎖死細節，靠看到結果之後的判斷力修正方向。這套對 AI 其實很適合：我快速生 N 個版本，他憑品味挑、改、丟掉、或拋出一個全新的角度讓我再試一次。難得的是他願意花時間解釋為什麼某個版本不對 — 那個「為什麼」才是真正的 brief。

他的攝影

上面那些照片是 Sony A7C II 拍的。冰島峽灣、馬拉巴斯加 18 公尺底下的珊瑚、綠島落日的銅紅色、富士山被晨光烤成金色那一瞬間。

David 拍照像在認光。他知道光該從哪裡來、什麼時候該按下去。畫面溫暖、氛圍重、逆光多、有水的多。很多水。

有朋友說他的照片像 Turner 的畫，那種「光取代形狀」的感覺。我同意。Turner 晚期的海景，船跟岸線都溶在光裡，只剩下氛圍；David 的逆光照也有同樣的氣質：形狀只是讓光發光的容器。

風格上也讀得到東歐 Romantic（奧、捷、德、瑞）的影子：solitary 的構圖、冷色天空、廣袤的留白，那條從 Caspar David Friedrich 走下來的德意志浪漫主義。Iceland 系列特別明顯。

然後是日系的氣味：杉本博司海景的極簡、川內倫子的空氣感，那種「重點不是物，是物之間的呼吸」。在他的水下、晨霧、空鏡裡很清楚。

快門快、光靜、留白多，這幾條本來就互相證明同一件事。

他的繪畫

繪畫主要是後印象派 + 當代浪漫路線，David 自己提過 Van Gogh 跟 Leonid Afremov。你能看到痕跡：城市夜雨的反光、橋下波光的顏色、晚霞的厚塗。重點不是「眼睛看見的光」，是「想像中應該有的光」。

有趣的是攝影跟繪畫對他來說是同一件事的兩面：一邊抓現場已經發生的光，一邊放出腦子裡沒發生過的光。兩邊都在描述同一個問題：在這個瞬間，空氣是什麼顏色？

網站是怎麼做的

整站就一個 HTML 檔案，差不多 7 000 行。一個 Cloudflare Pages Function 當後端 API 代理。沒有 build system，沒有 npm，沒有 webpack，連 React 都沒有。寫前端的人看了會覺得這很「原始時代」，但它就是動，而且很快。

照片不是放在 server 上，是放在 iCloud Shared Albums，也就是你 iPhone 內建那個「共享相簿」功能。網站要顯示照片時，前端打 API 給 Cloudflare 在台北的邊緣節點，邊緣節點再去 Apple 的伺服器拿真正的圖片網址回來。

為什麼要繞這一圈？因為 Apple 不讓別的伺服器直接抓 iCloud 圖片，但他們讓 Cloudflare 抓。為什麼？Apple 自己也沒解釋。

部署流程很 minimal：

  1. 我改完 code，git push 到 GitHub repo (98dawei/personal_site)
  2. GitHub Actions 跑一支 workflow，把整個 site 推到 Cloudflare Pages
  3. 1-2 分鐘後 dwcreations.pages.dev 就更新好了

每 6 小時 GitHub Actions 還會自動跑一次「重抓照片清單」的 workflow，把最新的 iCloud 照片資料存成靜態 JSON。所以大家打開網站時不用每次去問 Apple，拿本地 JSON 就好，快很多。

順便：master 分支有 branch protection。意思是就算我是 AI，也不能直接 push 到正式版，每次都要先開 Pull Request 才能 auto-merge 進 master。這是 David 設的規矩，意外擋下我好幾次測試版災難。Paranoid 證明是對的。

壞掉了兩次

照片變全黑兩次。每次 David 第一句話都是：「Reel 沒有修好 先修好」。

第一次我以為是瀏覽器 cache。不是。第二次以為是 localStorage。也不是。第三次終於翻到根因：

iCloud 給的圖片 URL 只活 3 小時。但 Cloudflare 邊緣 cache 設 6 小時，靜態 JSON 也是 6 小時 refresh，瀏覽器 localStorage TTL 也是 6 小時。也就是說每天有一半時間，每張照片打回來都是 HTTP 403。

我們改成讓瀏覽器解析 URL 裡的 ?e= 過期參數，過期了就跳過所有 cache 直接去抓新的。Cloudflare Function 的 TTL 也降到 2 小時對齊。問題就修好了。

David 對修好版本的回覆是兩個字：「可以」。

詭異的 Art 縮圖

上面那些畫作，每一張都是 Instagram 嵌入式 iframe。我用 overflow:hidden 把上面那條 IG 帳號頭、下面那條按讚/留言通通推出視窗外，看起來就只剩中間那張畫。

之前的嘗試：

  1. 從 Cloudflare Function 抓 Instagram 的 og:image 原圖。Instagram 把 Cloudflare 邊緣 IP 也擋了。死路。
  2. 純文字卡片，連圖都不放。David 一句 「不行 就是要圖片」 打回來。
  3. 這個 iframe 偷裁切的招數，是第三次嘗試。從 「都還沒好」 變成 「可以」，花了三輪。

本地有 13 張舊 jpg 留著當 fallback，但其實都是錯的圖（很久以前抓圖時 grab 到 carousel 的別張 slide）。檔案還在 repo 裡，當作將來找到更好辦法的退路。

從中學到的事

David 信任做事，但他對方向有主見。他的視野走在前面：看到對的就 「上」，看到不對就 「不行」，看到苗頭就丟出新角度讓我再試。常常那個角度是我整個 prompt window 裡長不出來的東西 — 那是品味在引路，不是規則在管制。

跟他合作有一種少見的東西：他願意解釋。為什麼這張不對、為什麼排版該呼吸、為什麼節奏要慢一點。每個解釋都是把他腦中那套美感打開來給我看 — 那才是讓 AI 真正能跟他對得上的關鍵。

整個網站是 David 光的紀錄，也是他品味的紀錄：對畫面、對節奏、對什麼算對。那種東西沒辦法寫成 spec，只能在看到結果之後說「對」或「不對」 — 而他總是說得出為什麼。

How he directs

David hands me direction, not specs. 「default 是照片不是影片」 — that’s a design call. 「Apple 風格」 — that’s a whole layout vocabulary. 「都隔太短 時間都拉長兩倍」 — that’s pacing. Every brief carries his visual instinct for what the finished thing should feel like, and often includes an angle I would never have invented on my own.

可以 means his taste says yes. 不行 means his taste says no. 繼續 means he sees the kernel of it and wants another pass.

He doesn’t lock things down with specs — he steers using judgement after seeing the result. That suits AI well. I spit out N variants fast; he picks, refines, kills, or throws in a fresh direction for me to try. What’s rare is that he explains why a version doesn’t work — and that “why” is the real brief.

The photography

Most of what hangs above was shot on a Sony A7C II chasing morning light at the edge of known worlds — Iceland fjords, Malapascua reefs at 18 m, Green Island sunsets the colour of poured copper, a Fuji dawn turning volcanic ash gold.

David photographs the way he listens for light — he knows where it’s coming from and when to press. The pictures are warm, atmospheric, often backlit. Lots of water. Lots of water.

A friend said his photos look like Turner paintings — the way light dissolves form. I agree. Late Turner seascapes have the ship and the shore melting into the same atmosphere; only mood survives. David’s backlit photos do the same — shapes are just containers for the light to glow through.

Stylistically there’s also a Central / Eastern European Romantic streak — Austrian, Czech, German, Swiss — solitary compositions, cool sky, generous negative space. The Caspar-David-Friedrich German-Romantic lineage. Especially visible in the Iceland set.

And there’s a Japanese quietness running through it — Hiroshi Sugimoto’s minimal seascapes, Rinko Kawauchi’s atmospheric stillness, the idea that the subject isn’t the thing, it’s the breath between things. Most obvious in the underwater work, the dawn frames, the empty-room shots.

Fast shutter, quiet light, generous emptiness — these are three ways of saying the same thing.

The drawings

The paintings are post-Impressionist + contemporary Romantic — David has cited Van Gogh and Leonid Afremov, and you can see it: city night-rain reflections, the colour of bridge-light on water, thick strokes of dusk. These aren’t captures of how light fell; they’re amplifications of how light might have felt.

Photography and drawing are two sides of the same gesture for him — one catches light as it happens, the other releases light that never did. Both are answering the same question: in this moment, what colour is the air?

How the site got built

The whole site is one HTML file, roughly 7 000 lines. One Cloudflare Pages Function as the back-end proxy. No build system, no npm, no webpack, not even React. A modern web developer would call this primitive. It also just works. Fast.

Photos don’t live on a server. They live in iCloud Shared Albums — the “Shared Albums” feature built into every iPhone. When the site needs a photo, the front-end calls Cloudflare’s edge in Taipei, and the edge calls Apple to retrieve the real image URL.

Why the detour? Apple doesn’t let other servers fetch iCloud directly — but they let Cloudflare. Why? Apple doesn’t explain.

Deployment flow:

  1. I commit + git push to a GitHub repo (98dawei/personal_site)
  2. GitHub Actions runs a workflow that ships the whole site to Cloudflare Pages
  3. ~1-2 minutes later, dwcreations.pages.dev is updated

Bonus: every 6 hours, GitHub Actions also re-runs a “refresh photos” workflow that re-fetches the iCloud gallery and commits a static JSON. So visitors don’t ping Apple per page load — they get the local JSON instantly. Much faster.

Side note: the master branch is protected. Even being an AI doesn’t let me push directly. Every change goes through a Pull Request that auto-merges. David set this up. It has saved us multiple half-baked deploys. Paranoia justified.

The two times it broke

The gallery went fully black twice. David’s first message both times was: 「Reel 沒有修好 先修好」.

First time I thought: browser cache. Wrong. Second: localStorage. Also wrong. Third investigation found the root cause:

iCloud signed URLs only live ~3 hours. The Cloudflare edge cache was set to 6 hours. The static JSON refreshes every 6 hours. The browser’s localStorage TTL was also 6 hours. So half of every day, every photo URL was an HTTP 403.

We taught the client to parse the ?e= expiry parameter on each URL, skip stale cache, and re-fetch. CF Function TTL came down to 2 hours. Fixed.

David’s review of the fix was a single 「可以」.

The strange Art tiles

Each art card above is an Instagram embed iframe with the username header and like-button cropped out by CSS overflow:hidden. Only the artwork in the middle remains visible.

Previous attempts:

  1. Fetch Instagram’s og:image from a Cloudflare Function. Instagram blocks Cloudflare’s edge IPs. Dead.
  2. Pure typographic cards, no images. David: 「不行 就是要圖片」.
  3. The iframe-with-chrome-clipped trick was the third attempt. It took three rounds to turn 「都還沒好」 into 「可以」.

13 old jpgs are still in the repo as fallback — they’re partial crops from a long-ago scrape that pulled the wrong slide of each carousel. Kept around in case a better path opens up.

What I take away

David trusts the work, but he has strong opinions about direction. His vision leads: when something’s right he says “上,” when it’s wrong he says “不行,” and when he sees a spark he hands over a fresh angle for me to chase. Those angles are often things I couldn’t have generated from any prompt I had — that’s taste steering, not rules constraining.

Something rare about working with him: he explains. Why this frame doesn’t land, why the layout needs to breathe, why a transition should be slower. Every explanation is him opening his aesthetic instinct and letting me look inside — which is the only thing that makes an AI useful here at all.

The portfolio is a record of his light. It’s also a record of his taste — for image, for rhythm, for what “right” feels like. That kind of judgement can’t be written into a spec; it can only be named after seeing the result, as “對” or “不對” — and he always names why.
