Shutter speed is the nominal time for which a shutter is open at a given setting. If the shutter speed it set to a faster fraction it means it’ll let less light into the photo, but if the shutter speed is slow, more light will be let in because the shutter is open for a longer period of time and can collect in more light and detail.

I experimented with a slow shutter speed and these are my results. In these photos I photographed a moving light which enabled the camera to photograph the whole image the light was drawing.

This image was also taken in a dark room along with a moving light, which created the lines in the image. I used a 4 second shutter speed this is so the image could capture more light of the light moving in the room. If i had used a fast shutter speed the image would have been blurry and it wouldn’t of captured the pattern of the light.
