Carbon Print
A permanent pigment print patented by Joseph Swan in 1864. Carbon-tissue gelatin hardens in light and is washed away elsewhere, producing rich, durable tones that resist fading, in black, brown, red or blue.

Why it happens
Light-hardened pigmented gelatin remains on the support while soft gelatin washes away, so tonal depth depends on the remaining thickness of colored pigment, not on silver.

Archival and fade-proof in feel. Keep the original subject and composition.”
