NOSTALGIA

Low-pass filtered memories. Daguerreotype decay. Music box harmonics winding down.

Low-pass filters, photographic decay, music box harmonics, carousel functions, and remnant signals. The mathematics of memory — blurred, warm, and slowly losing resolution.

▶The Story Behind This Series

Nostalgia is memory with its high frequencies removed. The details blur but the warmth remains. A low-pass filter does exactly this — it removes sharp edges and rapid changes, leaving only the slow, smooth underlying signal. This series renders that filtering as visual art.

Mathematical primitive: low-pass filtering, harmonic decay, photographic degradation
