!!Con 2017: HDR Photography in Microsoft Excel?! by Kevin Chen
Confreaks
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.
