中文导读
!!Con 2017 上的趣味短演讲，Kevin Chen 把 HDR 图像经典算法转化为线性方程组，并直接在 Microsoft Excel 电子表格里纯手工算了一遍，零图像处理基础也能轻松看懂。
为什么 HN 推它
短小精悍且充满极客恶趣味的演讲，用最荒诞好玩的方式把 HDR 摄影原理彻底拆白。
「短小好玩，向所有 HN 读者安利这个演讲。」HN 网友原话：It's short and fun, I recommend it to all HN readers.
英文原摘要（HackerTube / Claude 整理）
A short conference talk from !!Con 2017 in which Kevin Chen explains the HDR imaging algorithm from a foundational paper, framing it as a system of linear equations, and implements it in a Microsoft Excel spreadsheet. No prior image processing knowledge is needed.
HN commenters recommend it as a fun, short talk that shows how HDR photography actually works through an absurdly playful implementation.
HN 上的提及
My favorite talk from this year was about implementing an algorithm for HDR photography purely in Microsoft Excel
Included in a list of favorite 2017 talks
I just watched a talk this morning about doing high dynamic range photography in Excel
things like this are a really interesting way to show how things like HDR photography actually work
It's short and fun, I recommend it to all HN readers.
