What is ISO? What is it for?

The ISO also known as photographic sensitivity scale It is the tool that merges both the ASA and the DIN. It is the scale that defines the amount of light required by a camera when taking a photograph.

In simple words, ISO is the capacity of a camera’s sensor when capturing light.

As soon as it is, we will know that the light input will be the exposure and the output will represent the acquired density. So if you modify the sensor of your camera keep in mind that you could be making it more sensitive or less sensitive to light.

The obturation and the diaphragm let the light pass gently through the camera lens almost naturally. If you still don’t know how to control and regulate the shutter speed of your camera, this article is of interest to you. On the other hand, the ISO intercepts the light and amplifies it digitally, making the most of it. Bear in mind that if you don’t use this tool carefully, you can lose the quality of your image.

Camera settings

If you want to capture Photographs that impact due to their good quality, you must learn to handle this valuable tool perfectly.

You always want to have a good image, but if we are not careful when configuring a camera you could alter the values. Modifying the ISO sensitivity will be reflected in the exposure of the image and the existence or absence of noise in it.

It is recommended that you keep the ISO of your camera at a low level either in ISO 100 or ISO 200. This will totally depend on the camera you have, but there are times when using more of this is necessary.

Like when you are in a dark place or when you want to freeze a moment or when you hope to capture a starry night. It may be that opening and closing the diaphragm for these shots is very difficult, that is why the ISO exists in your camera.

Noise when increasing the ISO?

ISO boost

Increasing the ISO sensitivity of an image may generate a bit of noise, what do we mean? The noise is represented in small noticeable pixels or grains in the shaded parts of the images.

So the higher we raise the ISO levels, the more noise in the image. This due to amplification occurs with a weak light base generating loss of quality in the image.

But don’t think that using a high ISO is wrong, you really just need to master the technique of use. Do not worry if in the first attempts your shots do not come out as you expect you should know your camera a little more.

This way you will know how much of ISO it is the ideal considering that noise is part of photography. Although there are many programs that promise to help you eliminate this «problem», the truth is that they only remove definition from the images.
