Automatic 100: Basics of Function

1 - closed

The Model 100 was the first of many Polaroid pack film cameras. It set the standard for the basic body, shutter assembly and finders found on all others.

While there are many pack film models, there are few differences when it comes to cleaning and modifying the batteries.

The ubiquitous nature of the 100, and many that share its finder and shutter, makes it an easy pick for a quick reconditioning and battery conversion. If you have a model with a folding finder, and a scene selector on your shutter, than these pages will work fine for you as well.

This model uses a single 4.5v battery. The originals are hard to find and expensive. If you find that your model also requires 4.5v batteries, then these pages will also work for you.

1 - unclasp

The first thing to get the camera open is to open the front clamshell. And to work on the camera, simply remove it by the clasp found inside.
