ISO
ISO is a camera setting that controls the sensitivity of the camera's sensor to light. The higher the ISO setting, the more sensitive the sensor becomes, and the less light is required to produce a properly exposed image. The lower the ISO setting, the less sensitive the sensor becomes, and more light is required to produce a properly exposed image.
When you're taking photos, you want to use the lowest ISO possible to produce the best image quality. This is because using a high ISO setting can introduce noise, or grain, into the image, which can make the final image look less sharp and less detailed. However, there are situations where using a higher ISO is necessary, such as in low light situations.
One of the main benefits of using a low ISO setting is that it produces images with less noise. This is because the sensor is less sensitive to light, so it doesn't pick up as much noise from the environment. This is especially important when shooting in low light conditions, as noise can be more pronounced in darker environments.
On the other hand, using a high ISO setting can be beneficial in low light conditions. When there is not enough light to produce a properly exposed image, you can increase the ISO to make the sensor more sensitive to light. This allows you to take photos in darker environments without having to use a flash or a tripod.
It's important to note that increasing the ISO also increases the shutter speed, so the image will be less blurry if the subject is moving. This can be especially helpful when shooting sports, wildlife or events where the subjects are moving quickly.
In conclusion, ISO is an important camera setting that controls the sensitivity of the camera's sensor to light. The lower the ISO, the less sensitive the sensor becomes, and the less noise there will be in the final image. However, using a higher ISO can be necessary in low light conditions, allowing you to take photos without using a flash or a tripod. It's important to find the right balance between ISO, shutter speed and aperture to get the desired result.
