After discussing Triangle Exposure, now we will explain each element of Triangle Exposure. In this case we will explain about ISO.
ISO is the ability of a camera to capture light. When setting up ISO, you must understand the basic functions of using ISO.
When you set the ISO higher, the light captured by the camera will become greater and the camera will become more sensitive and there will be more noise .
The ISO units themselves consist of ISO 50, 100, 200, 800, 1600, and others in ISO units. ISO not only makes the process of taking pictures with the right light easier, but using a very high ISO can also make photos noisy .
Noise is small spots that we can find in photos. Usually this noise will make the photo not of good quality.
In essence, when determining the right ISO, you should use the lowest ISO possible for better photo quality, and don't forget to consider the elements of Shutter Speed and Aperture.
