What is dip-and-dunk photo booth processing?
Reviewed by Booth Beacon · Verified 2026-08-25
Quick Answer
Dip-and-dunk refers to the mechanical system in analog photo booths where exposed photographic paper is moved sequentially through immersion tanks filled with liquid developer, bleach, clearing agent, and fixer via a motorized rack driven by a central camshaft.
Full Answer
Unlike continuous roller-transport processors that pull paper through tight squeegee rollers, a dip-and-dunk photo booth uses a mechanical carrier arm or dipping basket. Driven by a synchronous electric motor and geared camshaft, the paper is submerged into each chemical tank for a precisely calibrated duration before being lifted and dunked into the next bath.
