膜狀時間：影像物質性的刮擦、侵蝕與消逝

Membranous Time: The Erosion and Disappearance of Image’s Materiality

在數位技術普及的今日，具備物質載體的影像逐漸遭到汰換或棄置，並隨時間衰變與瓦解。然而，在過去由類比技術主導的時代，影像生產與物質的形塑密不可分；因此，物質條件即成為影像生成與變化的基礎，並直接影響影像的可見性與感知經驗。本文將聚焦於影像的物質性，視其為與可見影像共存的核心，造成有別於一般再現機制的美學實踐。從實驗電影對膠卷表面的刮擦與磨損的操作出發，探討物質—感知的直接交互；同時，亦透過對拾獲影像的思考，釐清自然時間對影像載體的侵蝕與衰敗，如何形塑一種存在於膠卷的「膜狀時間」；最終更試圖將物質與影像，視作歷史、記憶與遺忘彼此匯聚之場域，反思媒介和事物之間的消逝過程。

In today's era of widespread digital technology, images with physical carriers are gradually being replaced or discarded, decaying and disintegrating over time. However, in the past, when analog technology was dominant, the production of images was inseparable from the shaping of physical materials. As a result, material conditions became the foundation for the generation and transformation of images, directly influencing their visibility and perceptual experience. This paper focuses on the materiality of images, considering it as a core element that coexists with visible imagery, generating an aesthetic practice distinct from conventional representational mechanisms. Beginning with the experimental film techniques of scratching and eroding the film surface, it explores the direct interaction between materiality and perception. At the same time, through reflections on found images, it seeks to clarify how the erosion and decay of image carriers by natural time shape a form of ''membranous time'' embedded within film. Ultimately, it attempts to position material and image as a site where history, memory, and forgetting converge, reflecting on the process of disappearance between media and objects.
