What Is A Film Roll & How To Use It?  

Film rolls are a thin layer consisting of components like cellulose acetate or plastics. Furthermore, an emulsion, a light-sensitive liquid with silver halide crystals floating in a gelatinous layer, is applied to this base as a coating.

How To Use Film Rolls?

First of all, you must have a specific film roll along with a compatible camera to use with. There are three major steps of using film rolls stated below.

  • Installing Film Rolls

Initially, you need to feed the film leader to a take-up reel before the film cartridge or roll is placed into the camera’s film chamber. 

Afterward, wind the film onto the spool using the film advance mechanism, making sure it is tightly attached and ready for exposure. 

  • Advancing Film Rolls

You need to advance the film by a single frame after each exposure or shot. On most cameras, you can manually get this done by rotating a film advance wheel or knob. Automatic film advanced systems are available in better cameras. 

A new, unexposed frame is placed for the next shot when the film is advanced, moving the captured frame into a secured cartridge or spool. In similar ways, you can take shots and advance the film rolls until the film roll is completed.

  • Rewinding & Removing Film Rolls

The film gets detached from the take-up spool by a rewind knob or button on the majority of cameras. It allows it to be coiled back into the protective cartridge. 

Once you have a rewound film roll, you will feel resistance while rotating the knob. Lastly, remove the film roll from the chamber and send it to a professional lab for development into a physical print of the image.

Types Of Cameras That Use Film Rolls

Despite the rise in popularity of digital cameras in the past few decades, cameras using film rolls provide a one-of-a-kind experience in photography. Here’s a list of some widely used film cameras.

  • 35mm/small format camera
  • 120mm/Medium format camera
  • Large format camera
  • Toy film camera
  • Point-and-shoot camera
  • Instant camera
  • Polaroid camera

How To Know When Your Film Roll Is Done?

Knowing when your film roll is fully exposed and removing it is a very crucial thing to do. Otherwise, you’ll end up messing with the exposed films and ruin the roll.

35mm or Small Format Cameras

The SLR cameras with a 35mm film roll cartridge were used to rule the world of photography until the DSLR cameras took over.

When its film hits the last frame you will find that it is not advancing when you pull the advance lever. It will show resistance, meaning that your film roll is done and needs to rewind and unload from the canister.

Besides, most SLR, point & shoot cameras come with a frame counter which advances with each shot and shows the total number of shots taken. Generally, it starts from 0 and ends at 25. You can keep track of your film roll using this frame counter and know when it is done.

In compact point-and-shoot cameras, a digital indicator shows you the frame count letting you know if the film roll has any frames left. Apart from these some SLR cameras have a small red window/marker that shows the number of exposed film.

Medium Format Cameras (120)

The 120 film rolls used in medium format cameras have a range of 12-16 exposures per film. It depends upon the width of the image depending on which the total exposure number varies. 

The most common camera of this type is the TLR or Total Lens Reflex camera. Similar to the 35mm cameras, you can feel the film advance lever to know if it’s done or completed. A tension or slight resistance from the opposite side will tell you that the film roll is completely exposed to shots.

TLR cameras mostly come with a mechanical frame counter. You can also utilize it to know at what stage your film roll is. Besides, small transparent windows on the back let you take a peek at the take-up spool. While winding up the roll, it will show a slower movement meaning the film roll is likely finished.

Some film rolls come with frame markings. It could be either an arrow or a line. You can observe the markings through the transparent window at the back cover to understand at which stage the film roll is currently present.

Another way is to keep track of the paper backing of the 120mm films. The 120 films with 61mm width and a paper backing, need winding forward until all of the paper is on the take-up spool. Afterward, it is safe to open the camera cover and remove the film from the chamber.

If you have Kodak Instamatic cameras that take 126 films, will follow a similar concept. You keep on winding until the paper backing can no longer be seen in the window. Ensure to follow the steps only after the last exposure.

Large Format Cameras 

Unlike 35mm and 120mm cameras, large camera film comes in the form of individual sheets. The sheets are available in different sizes such as 4×5, 8×10, and 5×7 inches.

The number of films depends upon the capacity of the film holders of the camera. However, most large format cameras come with a film holder having a maximum capacity of 2 films or sheets. 

A film holder consists of two dark sides which are colour-coded. It is used to determine whether the film inside is exposed or unexposed. 

However, most photographers use the white/silver side to denote it as exposed and the dark side as unexposed. This trick helps you understand if your films are used or ready to take a shot.
