Shutter speed is the length of time your camera shutter stays open while you capture the image the more light that is allowed in to hit the sensor and the longer the camera shutter stays open the brighter the image is.
Shutter speed is measured in fractions of a second. 1/2000 would be a fast SS whereas 1/30 would be slow. The slower the shutter speed the more light can be accessed as well as the colours making the image more detailed and brighter.
I took some similar images while experimented with different shutter speeds.
I edited this image by cropping it and using sharpness tool on photoshop.
We also experimented with boxing and looked at the motion that was created with that. I then edited these photos on lightroom classic and photoshop.
