What is ISO in photography?

ISO stands for International Standards Organization, and it’s a measure of the sensitivity of a digital camera’s image sensor. In photography, ISO is used to determine the amount of light needed to capture an image.

The lower the ISO number, the less sensitive the sensor is to light, meaning you need more light to capture a good image. The higher the ISO number, the more sensitive the sensor is to light, meaning you need less light to capture a good image.

ISO can be adjusted in most digital cameras. It’s important to pay attention to the ISO setting when taking photos because it can affect the overall quality and sharpness of your image. A higher ISO can result in grainy photos, while a lower ISO will produce clearer images.

It’s also important to understand how ISO works with other settings on your camera. For example, if you’re shooting in low light and you want to freeze the action, you’ll want to use a higher ISO setting and a faster shutter speed. On the other hand, if you’re shooting in bright light and want to capture more detail, you’ll want to use a lower ISO setting and a slower shutter speed.

All in all, ISO is an important setting when taking photos and it’s important to understand how it works in order to get the best results.
