How does Fujifilm work?

Published in Instant Photography Technology 3 mins read

Fujifilm, a global company known for diverse products, operates through various divisions including imaging, healthcare, and materials. However, based on the provided reference, we can specifically explain how Fujifilm's Instax instant film works.

Fujifilm's Instax instant cameras produce photos that develop right before your eyes without needing a darkroom. This is achieved through the specialized design of their integral film.

How Instax Instant Film Develops

The magic happens within the Instax film sheet itself. It's a sophisticated chemical process that is initiated as the film is ejected from the camera.

The Role of Integral Film

Integral film, the kind of instant film used by Instax, is specifically engineered to contain all the necessary components for development and fixing within each sheet.

Here's a breakdown of the key elements and process based on the reference:

  • Layered Structure: The film contains layers of emulsion dye and layers of developing dye sandwiched within its “sheet.” These layers are sensitive to light. When a picture is taken, light hits the film, creating a latent image in the emulsion layers.
  • Chemical Pod: Developing and fixing chemicals are stored in the “sack” of white border on the bottom of the image. This is a crucial part of the instant development process.
  • Ejection and Spread: When the film is pushed out of the camera, it passes between two rollers. These rollers apply pressure to the film sheet. This pressure breaks the chemical sack in the border, releasing the developer chemicals.
  • Chemical Reaction: As the rollers spread the chemicals evenly across the film layers, a complex chemical reaction begins. The developer acts on the light-exposed emulsion layers, causing the image to appear. Other chemicals fix the image, making it permanent and preventing further development.

Essentially, the camera acts as a light-capturing device, and the film sheet acts as a self-contained chemical processing lab that activates upon ejection. This intricate design allows you to watch your photo emerge within minutes.

This instant development process is unique to integral films like Fujifilm Instax, providing the immediate gratification that makes instant photography popular.
