It’s so important to understand about exposure triangle because nowadays, the world of photography is growing rapidly. The development reached out the mobile phones. It means that mobile phone cameras also use the features like professional cameras.
So, what exactly exposure triangle is what is the element in exposure also how the relationship between the element? Here’s the explanation.
What is Exposure Triangle
An exposure triangle is a mention of 3 combination of elements which has an important role in lighting a photo. These three elements are very influential to the result of the photo. You can get a great photo or not as well.
The point of this combination is to balance the intensity of light which is entering the camera using 3 different methods. Such as aperture, shutter speed, and ISO.
Even though they have different functions, you should use a combination of these elements. Because they are interrelated. If one of these elements changes, it will impact the other two elements. Detailed information on these three elements is below.
Three Elements of Exposure Triangle
The above information has explained that there are three pillars of the exposure triangle, such as:
1. Aperture
It is the diaphragm in the camera lens. The function of the diaphragm is to set the DoF or depth of field of the object. If the aperture is small then the DoF will be wide. While if the lens aperture is large then the DoF will be narrow.
2. Shutter Speed
Is the time for the camera shutter to open and expose the light into the camera sensor? If you use a slow shutter speed, there will be more light coming in. On the other hand, if you use a high speed, there will be less incoming light. It will help to freeze the movement of the photo object.
3. ISO
The ISO on the camera indicates the level of sensitivity of the camera sensor to the light. A low number will make the camera’s sensitivity to light lower. While a high number will increase the sensitivity of the camera. The result of the photo will not be smooth due to the large noise or grain. Learn about the camera exposure triangle related to ISO to know more about ISO.
Relationship between Aperture, Shutter Speed and ISO
If you are interested in photography, then you have to learn about cameras’ basic lessons. One of them is the technique of using three exposure elements. These three must work together to produce the appropriate light intensity for the camera sensor. The point is the light that enters the sensor can’t be too bright and too dark.
You need to know that when the light is too dark, the result of the photo will be darker. Meanwhile, when the light is overexposed, the result in the photo will be more bright than it should be.
When using these three important elements in the exposure you will get a certain exposure value for a particular setting. As the explanation above, if one element changes, it will impact the other elements.
For example, when you increase the f/number, it means that you reduce the aperture. It will make the light coming to the camera sensorless. But you have expanded the focus of DoF (Depth of Field).
If you reduce the shutter speed, it will affect how the camera captures the movement. So it will cause the background or object to become blurry. However, the light entering the sensor will increase and the photo will be brighter.
Then what about ISO? If you set the number to a high value then it allows you to take photos in dim light. Unfortunately, with this setting, the result of the photo will be more noisy or grainy. That’s why you need to combine these three elements of the exposure triangle to achieve the perfect and amazing photo.
