如何將攝影課程大綱轉化為曝光三角課程
攝影學習者常常將光圈、快門和ISO視為彼此孤立的定義。這個課程把取捨關係可視化，讓他們能為真實場景選擇設置。
設計難題
源大綱需要同時保留三個變量及其結果。設計採用直接對比，而不是線性講授。

將源決策轉化為視覺路徑
- 01
明確一個拍攝問題
用一個場景為三個變量賦予具體目的。
- 02
並列展示變量
光圈、快門和ISO始終同時可見，而不是依次出現。
- 03
展示取捨關係
觀眾能看到一個控制項改變時，哪種視覺結果會隨之變化。
- 04
給出首次選擇規則
課程以一個簡單的判斷方法結束：先調整什麼。

為什麼這種視覺治療適合
並列對比本身就是教學工具：它讓學習者查看關聯變量，同時不丟失當前場景。

從自己的文件開始
- State the learner decision before listing concepts.
- Keep variables visible in the same frame when they affect one another.
- Close with one practical starting rule, not every advanced exception.
英文旁白
視頻翻譯
- 01The exposure triangle begins with a practical question: how can one scene become readable through camera settings?
- 02Aperture, shutter speed, and ISO work together, each changing brightness or motion in a different way.
- 03The comparison holds the subject constant so one variable can be observed without guesswork.
- 04A darker frame shows too little exposure, while the balanced frame preserves useful detail.
- 05Shutter speed adds another choice: more light can also introduce visible motion blur.
- 06The viewer checks one change at a time, rather than changing every setting together.
- 07That sequence turns the course outline into a repeatable practice path for new photographers.
- 08Use the original course material to confirm settings for your own scene and camera.
