When I mention film speed, I refer to the film’s light sensitivity in different photography.
Nowadays, most photographers, professionals, and beginners enjoy digital cameras for capturing moments.
But, what is the equivalent of film speed in digital cameras? This is crucial.
The ISO system features a solid connection between the camera’s lighting and exposure. Thus the ISO rating is equivalent to film speed in modern cameras.
Still, setting the film speed is like putting the camera’s exposure indicator.
Additionally, digital cameras use different ISO numbers for various photography and settings like slow, medium, and high speeds.
Some cameras can swap the rate while others cannot.

What Is The Equivalent Of Film Speed In Digital Cameras?
Generally, film speed is the same as ISO sensitivity in advanced photography. Therefore, ISO is the measurement of light sensitivity entering the digital camera sensors.
The ISO rating usually comes labeled on the camera package or the film casing.
Since ISO comprises several digits describing the light sensitivity of a film, it can make the best exposure.
Therefore, a photographer can modify the aperture and speeds of the shutter and film.
In simple words, the ISO setting affects other camera settings to achieve the best exposure.
Conversely, low film speed means that the camera is slow and is poor to light sensitivity, while quick ISO speed has better light sensitivity in the film.
Mostly, you’ll notice that high-end cameras feature 20 to 6400 ISO rates.
Check out below the different ISO ranges and what they mean;
20 to 200 is the usual low-speed film’s ISO rating. They work best when taking pictures when there’s too much light exposure, preferably outdoors.
The slow speed provides clear images because the camera lens shoot with much precision. So, low speed creates images with less grain.
Better still, if you have plans of making the image bigger anytime later, ensure you use the least ISO rating while shooting.
Tip: Because of the low speed and much precision, the shooting may take time. So, placing your camera on a tripod would help any shaking.
It’s also called ISO 400 film, and it’s the best ISO setting for overall camera usage. Medium speed works for both outdoor and indoor lighting settings.
Nonetheless, this speed setting is not ideal for extreme conditions and specialized photography.
Usually, high-speed ISO is from 400 to 6400. Remarkably, these cameras have excellent flexibility, especially in low-light conditions.
Better still, high speed is incredible for capturing actions or fast-moving subjects.
Conversely, photos using high speed have more grain because of the bigger silver crystals in the band. The fast ISO makes these silver crystals attract light.
So, a higher ISO range equals photos with more grain.
Pros of a Quicker Film
A quicker film comes with several advantages.
- The best benefit is the wide selection of apertures and shutter speeds. So, you can easily adjust or stop the shutter speed and aperture respectively as you desire. For example, you can swap from 200 to 400 ISO film.
- Thanks to the super-fast shutter speed in quick films, the photographer can freeze the movement to minimize the blur in motion film.
- The quicker film also provides a greater field depth. Even though there are more grains in a quick film image, there’s a better mood that increases the exposure of the photo’s latitude.
Cons of a Quicker Film
Even with the excellent pros mentioned above, there are cons available too.
- A quicker film, as observed produces grainier images thanks to the reduced tonal gradation. The tonal gradation is a way of showing how colors weaken.
- The use of larger silver grains is more compared to low-speed films in producing images. A set of silver grains makes the image visible in the final print. The final copy print has a lower definition.
- The slower film features improved tone and sharpness compared to quicker film. Hence, a slow-speed film is always better due to the excellent aperture and shutter speed settings.
How to Get a Good Exposure
Once you press the shutter button, you initiate the exposure. The exposure regulates the amount of light that gets to the film when capturing an image.
An overexposed picture is too light, and an underexposed one appears too dark.
You can correct the underexposure and overexposure in a darkroom or computer. But this is possible only if you are using film.
Starting with good exposure is always best to avoid any corrections.
The amount and direction of light in the environment play an essential role.
Sometimes, photographers add light using flash or decrease using special lens filters for adequate light to reach the film or sensor.
Aside from light, you also need to consider camera settings like;
- Shutter speed
- ISO or film speed
Additionally, it’s subjective to state how “properly exposed” a photo is. Here’s why.
A photographer has the flexibility to either “underexpose” or “overexpose” as they desire in order to achieve a satisfying effect in the images.
Still, the lighting settings may not agree with the camera’s light meter under the best exposure.
Frequently Asked Questions
What Is The Speed Of The Camera with Film?
Usually, speeds are from 20 up to 3200. A low ISO number implies a slow film and less light sensitivity.
Also, a quick film implies more sensitivity to light.
How Do You Select A Shutter Speed Film Camera?
Generally, your shutter speed shouldn’t surpass your lens’ focal length when holding the camera with your hands to shoot.
For instance, a 200mm lens needs a faster shutter speed like 1/200th per second to achieve a sharp image.
Did you know that film speed can improve or damage a photograph? Probably not. Worry not.
After understanding what is the equivalent of film speed in digital cameras, as explained above, everything becomes clear.
Digital cameras include ISO, which determines the sensitivity of a particular film to light. Herein, there are other ISO fundamentals that help you to go deeper in photography.
