Understand the Exposure Triangle: Aperture, Shutter Speed & ISO

Exposure Triangle

The Exposure Triangle

It is a must-know knowledge for any camera owner or photographer. Exposure triangle is one of the most important things to consider when you take photos. With it you can control how much light is entering into the camera and how much light is allowed to enter into the sensor. It is also important to know the shutter speed and aperture to create the perfect photo. The higher you set the ISO, the faster the shutter speed and vice versa.

The exposure triangle shows that the amount of light in the picture depends on three parameters. These three parameters are: Aperture (f-stop), Shutter Speed (Seconds) and ISO. This triangle allows you to adjust the settings of the camera. The exposure triangle is a tool that helps you take photos with the right amount of light. You can set the aperture and the shutter speed to allow more or less light into the camera. By setting a low ISO you can adjust the amount of noise that appears in the image.

Shutter speed

If you want to create a great image it is important to know that the shutter speed determines how much light enters the camera.

Shutter speed is the time interval that opens and closes the shutter to let light through the lens and onto the camera’s sensor.

Shutter speeds range from 1/500th second (or 1/1000th of a second) to 1/8000th of a second, but usually, we use shutter speeds in the middle of these values, such as 1/500th of a second or 1/640th of a second.

Let us imagine that we want to take a picture with a certain light source. If we use a fast shutter speed, the light will be captured immediately and if we set the shutter speed to a slow speed, the light will be captured over a longer period of time. In the same way, when you are taking pictures with a tripod, you will need a slow shutter speed to avoid blurring. If you are not using a tripod, you can increase the shutter speed.

ISO

The ISO, this parameter is used to adjust the sensitivity of the sensor. There are different types of ISO, each one for a specific type of sensor, and the one that you will use on your camera will depend on your needs. You can find this information in your camera manual.

A high ISO means the camera is very sensitive to light. When you raise the ISO, you will see that the noise is also increased.

Noise is the undesirable effect of having too much light on the sensor, which can be caused by reflections and other factors. Noise, in turn, can ruin an otherwise good picture.

The best camera for a photographer, according to professional photographers, is the Nikon D7200. It has a 35mm full frame sensor and it offers a wide range of features.

In the next part of the series we will look at the technical aspects of photography.

Aperture

The aperture size is the size of the hole in the lens that lets light through. It affects the brightness of a photograph and is measured in f-stops.

A larger f-stop number means less light will reach the sensor or film. The smaller the f-stop number, the more light reaches the sensor or film.
