摄影乳剂是一种用于胶片的化学复合物，在光照下能够形成影像。阿涅斯的手工乳剂是本片的核心元素，经过她如同现代炼金术师般的精细制作。影片将多种乳剂置于对话之中：包括柯达Tri-X胶片、柯达3378高对比度胶片和阿涅斯的手工乳剂。结构上，影片由三种概念构成：从最灵敏的乳剂到最不灵敏的乳剂的曝光范围递减，从北向南的地理纬度递减，以及摄像机的物理下降。运动、光化敏感性与地理位置在影像中交织伴随，自制的声景为影片提供了背景。影像和音乐逐渐退化，最终呈现出无序的银卤化物和失真的音律，形成激烈的节奏。 　　A photographic emulsion is a photosensitive chemical compound used in film to create an image when exposed to light. Agnès' artisanal emulsion drives this work, crafted with the precision of a contemporary alchemist. 　　It establishes a dialogue between different emulsions: Kodak Tri-X, Kodak 3378 high contrast film, and Agnès' artisanal emulsion. 　　The film is structured by three concepts: the descent in photographic latitude from the most light-sensitive emulsion to the least, the descent in geographical latitude, filming from north to south, and a physical camera descent. Movement, photochemical sensitivity, and geography are intertwined throughout the footage, accompanied by a self-produced soundscape. The images and music gradually degenerate into violent rhythms of disordered silver halides and distorted sounds.
