FilmAnalysisFilmAnalysis · 照片背后的故事
从照片出发，读一段摄影史。故事和照片之间只是阅读上的联想，不代表照片的作者、相机或实际用的胶卷。
1841 年，塔尔博特为卡罗式摄影法申请了专利。它先在纸上得到负像，再用这张纸底片反复印出正像。
同一时期的银版照片每次只有一张，无法复制。卡罗式底片则可以印出许多张，同一张照片能同时出现在好几个地方。纸的纤维会让细节略微发软，这也是卡罗式照片常见的样子。
把同一张照片放进两种排版：一次单独占一页，一次与另一张照片并排。照片本身没变，看的人先注意到什么、看多久，可能就不一样了。
「不妨试试」是编辑设计的练习，不是史实。
故事卡与徽章分开收藏。为照片评分仍按原有规则收集徽章。
FilmAnalysis · Stories behind the frame
Read a little photographic history. These connections suggest ways to look; they say nothing about authorship, cameras or the physical film stock.
In 1841 Talbot patented the calotype. It made a negative on paper, and that paper negative could print positive after positive.
A daguerreotype of the same years was a single, unrepeatable object. A calotype negative could yield many prints, so one picture could be in several places at once. The paper fibres softened fine detail, which is part of how calotypes look.
Lay out the same picture twice: alone on a page, then beside another photograph. The image does not change, but what a viewer notices first, and for how long, may.
"Try this" is an exercise written by the editors, not history.
Story cards have their own shelf. Rating photographs still collects badges under the existing rules.
