Guide to Shutter Speeds and Exposure Time

Guide To Shutter Speed

In this guide, we’ll explain how shutter speed works. And, how to choose the right one for your shot.

The three things that will determine your exposure are film speed, aperture and shutter speed. The speed of the film dictates how much light the film needs. The aperture controls how much light comes through the lens. And the shutter speed then controls how much of that light hits the film. These three things always work together to produce your image.

The shutter speed, sometimes known as exposure time, determines the amount of time your film is exposed to light when taking a photograph. So, you always need to balance your aperture and shutter speed to get a correct exposure.

The general rule is you need to shoot with at least 1/60 to get sharp images when shooting handheld. It is best to use a tripod if you want to shoot with a slower exposure time as this will help reduce any camera shake.

Fast Shutter

Fast speeds are really good for freezing fast-moving subjects. You need to make sure you are using a fast exposure time if you are trying to take a sharp image of a fast subject. Different cameras have different options but commonly you can choose something like 1/500.

Higher ISO film will also allow you to utilise the faster shutter speeds as they are more sensitive to light.

Slow Shutter

Slow shutter speeds will visibly record motion. They are often used to create the effect of motion in an image. A moving subject captured with a slow exposure time will be captured as a blur across the image. Slow exposure times are also necessary when taking photos at night. They allow you to get enough light to expose your image correctly.

Be careful when using slow exposures without a tripod. The slower the shutter the more likely that you will have visible camera shake in the image.

Reading Shutter Speeds

Shutter speed is measured in fractions of a second. So, for example, 1/60 is read as one-sixtieth of a second. The bigger the second number in the faster the speed.

Typical shutter speeds you will see are; 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250 and 1/500.
