Instructions
Open the camera to load the film. This is done in different ways according to the camera model. For instance, the Holga toy camera has two clips that slide off, the back of the unit is removed, and film is loaded in a manner similar to the conventional 35mm camera. A Hasselblad camera requires film to be loaded into a removable film back and then attached to the camera body.
Compose your image. This is done through a conventional viewfinder (on models like the Holga toy camera or certain models of Mamiya camera) or with the use of a ground-glass viewing plate on twin-lens reflex cameras, such as Hasselblads. With the latter, the user composes the image by looking down onto the ground-glass area.
Focus your image. Medium-format cameras have a variety of ways to focus, ranging from automatic to manual. Older cameras may have a magnifier over the ground glass to aid the photographer in fine-tuning the focus.
Press the shutter release. This may be a separate cable release or a button on the camera body. This will expose your film. When the film is exposed, advance the film to the next frame.
When the roll of film is finished, advance the film until the roll is completely on the takeup spool. The tension on the film advance may release and become easier to move. Remove the camera magazine and remove the film. Most film varieties provide a sticky tab on the end of the film to prevent it from unwinding. Your film is ready to process.
