Here's how to advance the film in an Argus Model C3:
1. Shoot a photo: After taking a picture, the camera automatically advances the film to the next exposure.
2. Pull the film pack tab: There's a small tab on the film pack itself. Once you've taken all the pictures in a frame, pull this tab to move the film pack to the next frame.
3. Repeat: Continue shooting and pulling the tab until you've used all the frames in the film pack.
Important Note:
* The Argus C3 has a fixed focus lens and uses a built-in flash.
* It only takes 12 exposures per film pack.
* You cannot rewind the film in this camera. Once the film pack is used, you discard it.
