Most photographers, both beginners, and pros use digital cameras to take pictures these days.
But what does “film speed” mean when it comes to digital cameras? This is important.
The ISO system has a strong link between the lighting and exposure of the camera. So, in modern cameras, the ISO rating is the same as the speed of the film. Still, setting the film speed is the same as putting the exposure indicator on the camera.
Also, digital cameras use different ISO numbers for slow, medium, and fast speeds and settings like that.
Some cameras let you change the rate, but others don’t.

In Photography, What Does “Film Speed” Mean?
Film speed is a way to figure out how sensitive the film is. “Film Speed” was a term that was often used for older film cameras. On the box of film, there is always a number that tells you how sensitive it is to light.
For film cameras, the term “film speed” was used. For digital cameras, the term “ISO” is used instead. Based on what they do, there aren’t that many differences between them.
But you couldn’t change how sensitive the sensor was on a film camera as easily as you can now. If you wanted a different level of sensitivity, you would have to buy a different speed or sensitivity of film.
What is a Camera’s ISO?
Now that we know that ISO is what digital cameras use instead of film speed, let’s find out what camera ISO is.
ISO is a set of standard numbers that tells you how sensitive the film is to light. To get good exposure, you need to change the film speed as well as the aperture and shutter speed. ISO lets the camera decide what the other settings need to be to get good exposure.
High-end cameras have ISO speeds that range from 20 to 6400. A slow film with a low ISO speed is less sensitive to light, while a fast film with a high ISO speed is more sensitive to light.
What Is The Equivalent Of Film Speed In Digital Cameras?
Most of the time, ISO sensitivity and film speed are the same things in advanced photography. So, ISO is a way to measure how sensitive the digital camera sensors are to light.
Usually, the ISO rating is written on the camera box or the film case.
Since ISO is made up of several numbers that describe how sensitive a film is to light, it can be used to get the best exposure.
So, a photographer can change the shutter and film speeds and the aperture.
To put it simply, the ISO setting affects other settings in the camera to get the best exposure.
On the other hand, low film speed means that the camera is slow and not very sensitive to light, while fast ISO speed means that the film is more sensitive to light.
Most of the time, you’ll find those high-end cameras have ISO rates between 20 and 6400.
What else?
Check out the list of ISO ranges and what they mean below;
Low Speed:
The slow-speed film has an ISO rating between 20 and 200. They work best when there’s too much light, like when you’re taking pictures outside.
Because the camera lens shoots with a lot of accuracies, the slow speed lets you get clear pictures. So, pictures taken at a slow speed have less grain.
Better yet, if you want to make the picture bigger later, make sure you use the lowest ISO rating when you take the picture.
Medium Speed:
It’s also called ISO 400 film, and it’s the best ISO setting for general camera use. Medium speed works for lighting both outside and inside.
Still, this speed setting isn’t the best for extreme conditions or photography that requires a lot of skill.
High Speed:
Most of the time, high-speed ISO is between 400 and 6400. Surprisingly, these cameras are very flexible, especially when there isn’t much light.
Even better, high speed is a great way to catch the action or things that are moving quickly.
On the other hand, pictures taken at high speed have more grain because the silver crystals in the band are bigger. Because the ISO is so high, these silver crystals draw light to them.
So, photos with more grain have a higher ISO range.
Pros of a Faster Film?
There are many good things about a quicker film.
- The wide range of apertures and shutter speeds is the best thing about it. So it’s easy to change or stop the shutter speed and aperture as you want. You can switch from 200 ISO film to 400 ISO film, for example.
- In quick films, the super-fast shutter speed lets the photographer stop the action to reduce blur in motion films.
- The faster film also has a bigger depth of field. Even though a quick film image has more grains, it has a better mood that increases the exposure latitude of the photo.
Cons of a Faster Film:
Even though there are a lot of great pros, there are also some bad ones.
- As has been seen, a faster film makes images with more grain because it has less tonal gradation. The tonal gradation shows how colors get less intense.
- Images are made more like slow-speed films, which use larger silver grains. In the final print, the image can be seen because of a set of silver grains. The final print copy has less clarity.
- The tone and sharpness of the slower film are better than those of the faster film. Because of this, a slow-speed film is always better because it has better settings for aperture and shutter speed.
Getting a Good Exposure:
As soon as you press the shutter button, the exposure starts. When taking a picture, the exposure controls how much light gets to the film.
A picture that is overexposed is too light, and a picture that is underexposed is too dark.
You can fix too much or too little light in the darkroom or on a computer. But you can only do this if you use film.
To avoid having to make corrections, it’s always best to start with good exposure.
How much and where the light is in the environment is very important.
Photographers sometimes use flash or special lens filters to add or take away light so that enough light gets to the film or sensor.
Besides light, you also need to think about how your camera is set up.
- Aperture
- Shutter speed
- ISO or film speed
Also, it’s hard to say for sure if a photo is “properly exposed.” This is why.
A photographer can choose to either “underexpose” or “overexpose” in order to get the effect they want in their photos.
Bottom Line:
Did you know that the speed of the film can make or break a picture? Most likely not. Don’t worry.
Once you know what the digital equivalent of film speed is, as was explained above, everything makes sense.
The ISO setting on digital cameras lets you know how sensitive a film is to light. Here are some other basics about ISO that will help you get better at photography.

FAQs:
What Is The Speed Of The Camera with Film?
Most speeds are between 20 and 3200. A low ISO number means that the film is slow and doesn’t pick up as much light.
A quick film also means that it is more sensitive to light.
How do you choose a film camera with a shutter speed?
When shooting with your hands, your shutter speed shouldn’t be faster than the focal length of your lens.
For example, to get a sharp image with a 200mm lens, the shutter speed needs to be faster, like 1/200th of a second.
