A camera’s ISO setting determines how sensitive the sensor is to light. A higher ISO setting will result in a brighter image, but it will also introduce more noise into the image.
For this reason, photographers avoid using a high ISO setting unless necessary. However, there are some benefits to using a high ISO setting of 6400 in a DSLR camera.
– First, it can help to freeze fast-moving subjects.
– Second, it can capture images in low-light conditions without the need for a flash.
Finally, adding grain or other textures can give photos a unique look.
