Use of Shutter Speed while capturing waterfalls

For capturing subjects like waterfall, where capturing the flow of water gives an artistic effect, it is advisable to use a very slow shutter speed.

Effect of Shutter Speed on Motion Blur

Fast shutter speeds will “freeze” motion, while slow shutter speeds introduces blur and shows the movement

Shutter Speed Concept Illustrated

Shutter speed is the Measurement of the time the shutter is open, in seconds or fractions of a second. It is expressed as fractions of a second as 1 s, 1/2 s, 1/4 s … 1/250 s, 1/ 500 s. The faster the shutter speed, the shorter the time the image sensor is exposed to light and less is the exposure assuming rest all settings are same. Increasing shutter speed by one step halves the amount of time the shutter is open and vice verse.

Effect of Aperture on Depth Of Field

Smaller the aperture size greater is the DOF. Which also means higher the f stop, higher the depth of field. F16 will produce greater DOF than F8.
