• The aperture of the lens aperture (analogous to opening our eyes
when he saw the object distance or short distance) is usually in the size of f/2.8, f/5.6, f / 7, f/11, and so on.
• Shutter Speed is the speed of earlier aperture, shutter speed with respect to how long the light receiving lens when the diaphragm in the open; in size 1sec, 1/45sec, 1/125sec, 1/250sec, those that are 1 / 2000 sec and so on (sec: seconds / second)
The combination of both is a unique combination, the combination of which influence each other to produce an image that we want (and artistic of course).
The combination of Aperture and Shutter Speed can produce a Depth of Field (DoF) are diverse.
What's is DoF? Depth of Field is the depth range of the camera focus, DoF is a measure of the range of
