ISO is a fundamental aspect of photography that affects the final image's brightness and graininess. It's particularly important in film photography, where you set the ISO before loading the film into the camera.
In this blog post, we'll explore ISO on film cameras and how it affects your photos.
What is ISO?
ISO stands for the International Organization for Standardization, and in photography, it refers to the sensitivity of the camera's sensor or film to light. ISO is measured in numbers, with lower numbers indicating less sensitivity to light and higher numbers indicating greater sensitivity.
For example, an ISO of 100 is less sensitive to light than an ISO of 400. An ISO of 400 is less sensitive to light than an ISO of 800, and so on.
How does ISO affect your photos?
In film photography, you set the ISO before loading the film into the camera. Once you load the film, you cannot change the ISO until you finish that roll of film. Therefore, it's important to choose the right ISO for the lighting conditions you will be shooting in.
A low ISO, such as 100, is ideal for bright, sunny conditions. This is because the film is less sensitive to light, and you need to let more light into the camera to expose the film correctly. Using a low ISO in low light conditions will result in underexposed photos.
A higher ISO, such as 400 or 800, is more sensitive to light and is ideal for low-light situations or when you need a faster shutter speed. However, using
a higher ISO film can result in more grain in the final image, particularly when shooting in low-light conditions.
Graininess is a characteristic of film photography, and it refers to the visible texture or noise in the image. The higher the ISO, the more noticeable the grain will be. Some photographers embrace graininess as an aesthetic choice, while others prefer smoother, less grainy images.
How to choose the right ISO for your film camera?
Choosing the right ISO for your film camera depends on the lighting conditions and the desired effect. Here are some guidelines to help you choose the right ISO:
For bright, sunny conditions, use a low ISO, such as 100 or 200.
For overcast or cloudy conditions, use an ISO of 400.
For low-light situations or when you need a faster shutter speed, use an ISO of 800 or higher.
If you want a smooth, less grainy image, use a lower ISO.
If you want a grainy, gritty image, use a higher ISO.
In conclusion, ISO is a critical aspect of film photography that affects your photos' brightness and graininess. Choosing the right ISO for your film camera
depends on the lighting conditions and the desired effect. Remember that once you load a roll of film with a certain ISO, you cannot change it until you finish that roll of film, so choose wisely. With practice and experimentation, you'll develop a sense of how to use ISO to achieve the desired effect in your photos.
