Spectral Membranes is a dedicated period of research and development exploring the material and temporal thresholds of analogue film. Building on my Revenants series, the project probes the fragile interplay between light, time, and chemical processes, where emulsion decays, images flicker, and sound emerges from material instability. Working with specialist collaborators, I will refine reversal, toning, and contact-printing techniques while developing an essay-film framework that interweaves moving image and text. The project stages conditions in which images almost form and then slip, making perceptible the membrane between presence and disappearance. It is a continuation of my ongoing inquiry into how analogue processes expose the mortality, extraction, and entropy embedded in image-making, and how work can inhabit the spectral space between immersion and ruin.
