Shutter speed

How fast the shutter is open or how long its open

at night time and in a sports photo sometimes

in a fast moving object that you want a quick photo of and in day time

use slow shutter speed when u want a still image so that it dosent move when you click the button.

I feel like I have a really good understanding in shutter speed and I really like to use it in my photos. I can change the shutter speed depending on what Im doing and now I know how to do it which is a really good skill to have
