When you set the settings of your camera at maximum shutter speed you can create some sorts of amazing effects with proper use of light.
The shutter speed and aperture together helps to determine the amount of light that may reach towards the sensor of the camera.
Once the desired ISO (i.e) is set you may the light emitted by the surroundings can be controlled using shutter speed and aperture as well.
An amazing thing to be remembered that multiple combinations of shutter speed and aperture can give the same exposure value.
A shutter speed of 1/50 s with an f/4.0 aperture gives the same exposure value as a 1/100 s shutter speed with an f/2.8 aperture, and also the same exposure value as a 1/200 s shutter speed with an f/2.0 aperture, or 1/25th second at f/5.6.
You can allow camera to get light by small amount, you can increase the aperture (f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22…).
To do long exposure photography, the need of tripod is a must.
Since you are going to capture moments in the scene over time, you have to make sure that the camera remains steady during the time of capture in order to avoid blur and unstable photos and make the photograph weird.
