Inside the booth
How an analogue photobooth works
A camera, a moving paper strip, and a darkroom small enough to hide behind a wall.
The waiting time is not just a printing animation. In a chemical booth, the photograph has to pass through a physical process before it can be handed to the sitter.
Light reaches the paper
AUTOFOTO describes its machines pulling silver-gelatin paper from a light-tight roll and presenting it to the camera. A prism helps orient the image. The mechanism moves the strip between exposures. This describes the restorers’ machines, not the internals of all booths made in every decade.

A miniature processing line
After exposure, an arm carries the paper through a sequence of chemical baths, then to the delivery unit. AUTOFOTO’s account includes developer, bleach, clearing and toner stages. That is why ordinary negative-paper instructions cannot simply be substituted for the booth’s reversal process.

Observe without opening
To understand a machine, watch an operator’s demonstration or museum video. Do not open panels, handle chemicals, or force the delivery slot. Keep exposure, processing and output separate in your description. A modern app can imitate a strip’s layout and tone, but it does not recreate this physical silver-gelatin process.
