I know a bit of photography. If you decrease the number of shutter speed, the amount of light going into the lens increases and as a result of that, the lights become 'lines'.
How do I refer to such lights? I want to say -
I love ________ in this picture
If you want to have _____ lights, decrease the shutter speed of your camera.
Here is what I'm referring to.
One word that comes to my mind is 'shredded lights'. Kindly confirm or suggest something better.
