So there's an exposure element to it, it actually affects the lightness, brightness, or darkness of an image, but also how motion is portayed. So the longer the shutter speed, i.e. 60, 30, 25, going down, the number gets smaller, but the exposure time gets longer, that will make your motion blurry, okay? It'll make it more blurry.
