Film cameras are designed in different types and styles. However, despite their different models, all camera types share basic functions that define how they function. Understanding how your film camera operates can only raise the quality of your shooting skills to the next level.
Whether you’re using a large format camera or a vintage 35mm SLR, knowing the fundamental functions of film cameras can improve your photography and help you use your equipment effectively.
In this post, we’ll expound on the five basic functions of all film cameras and explain how each element contributes to the amazing capture of video shots.
Let’s dive in!
Basic Functions of All Film Cameras – Improve Your Photography Skills
1. Light Control: Aperture

One of the important elements of a film camera is its aperture. The aperture is simply the opening through which light enters the camera. Therefore, the wider the opening in your camera, the more light can pass through and reach the sensor, affecting the image’s exposure.
Similarly, the aperture in a camera is an adjustable diaphragm, commonly represented by f-stops such as f/2.8, f/8, and f/16. Its primary purpose is to control light exposure and depth of field.
But how does it work?
Generally, the f/2.8 aperture, representing a larger aperture in a film camera, permits more light to pass through the film, thus creating a shallower depth of field suitable for portraits. On the other hand, the f/16 aperture, which represents a smaller aperture, usually restricts light, enhancing the depth of a field suitable for landscapes.
Acquainting with aperture settings enables a photographer to achieve greatness by controlling exposure and creating artistic effects for amazing shots.
2. Shutter Mechanism
The shutter mechanism in a film camera is an important element. Its function is to manage motion blur and free fast-moving objects. This mechanism fundamentally determines how long the shutter is open to permit light to hit the camera’s sensor or to control the time the film is exposed to light.
In simple terms, shutter speed regulates the duration of light exposure in a film camera. This speed is measured or indicated on a dial as a fraction of a second, for example, 1/60 or 1/1000.
But how does it work in a second-hand camera?
Shutter mechanisms usually range from long exposure to quick snaps. In this case, long exposure might be 1 second or longer, whereas quick snaps might be 1/1000 of a second or faster.
Therefore, the faster the shutter speed in a film camera, the clearer the moving object. On the other hand, the slower the shutter speed, the more blurred the moving object might be because the object moves during the amount of time the shutter speed is open.
Knowing how to balance the shutter speed with an aperture in a camera leads to perfect exposure and well-composed images. Faster shutter speeds work best for amazing wildlife photography or spots. On the other hand, longer shutter speeds are the most suitable for low-light scenes.
3. Composing the Shot: Viewfinder
Have you ever wondered why a photographer might capture shots without unwanted elements in the final scenes or images? This is where the viewfinder comes in.
Generally, the viewfinder permits photographers to see and compose the shot even before pressing the shutter. Certain models might have a separate waist-level finder or rangefinder, but often, a film camera uses the optical viewfinder to capture desired shots.
Therefore, this element in a second-hand camera works by projecting an image through the lens (in SLRs) or via rangefinders, a secondary optical. Nonetheless, a parallax error might occur, particularly in non-SLR cameras at a close range, because of the variation between what the lens captures and what the viewfinder shows.
4. Focus
The clarity and sharpness of a film camera are brought about by proper focus when shooting. On the other hand, poor focus leads to unwanted images, which are always rendered unusable. This means you must recognize the power of proper focus as a photographer in film photography.
So, to ensure the clarity and focus of shots in second-hand cameras, film cameras require automatic or manual focusing to ensure that the subject in question is clear. This technique brings various scene elements to attention based on the photographer’s intent.
How does the film camera execute the focus mechanism?
Photographers must keep adjusting the focus ring until the subject is sharp and clear for manual focus. However, modern film cameras’ autofocus systems usually detect the subject’s distance and adjust the focus accordingly.
Therefore, knowing focus mechanism techniques in second-hand cameras helps a photographer capture and produce quality shots, images, and videos.
5. ISO Setting
ISO is another core element every photographer must know about a film camera. This component is essential for determining the film’s sensitivity to light, usually called the camera sensor’s sensitivity.
In film cameras, ISO is set by the genre of film used. However, digital photography can adjust this setting electronically for effective image capturing. Therefore, the more ISO you have on your film camera, the more your camera’s sensor will improve image brightness.
However, grains might be added to compensate for insufficient light. Therefore, you’re advised to keep your ISO as low as possible to lower the amount of shot distortion.
Why The Above Film Camera Functions Are Essential
Generally, each element in a film camera, including ISO, aperture, shutter, and focus mechanism, plays a pivotal role in ensuring the entire process of film photography is flawless. Additionally, integrating the above functions in a second-hand film camera provides photographers with a complete range of control over their photographic end products.
Therefore, to make the most out of film cameras, it is crucial to understand all the details of second-hand film camera practices and become well-versed in each for amazing film photography results.
