The sensitivity of the following values is iso100.

This value table is very useful, not to mention its eV. Single View shutter and aperture.
In ev10, (aperture f/2.8, shutter is 1/250) (aperture f/4.0, shutter is 1/60) (aperture f/5.6, shutter is 1/30)... and so on.

What does this mean?
When the sensitivity and field light (ev10) remain unchanged, the aperture is reduced and the shutter needs to be increased (slow ).

When the exposure value is negative, it is low light, and when the exposure value is positive, it is high light.
F-number = aperture Value
8 m = 8-minute shutter Value
8 = 8 seconds shutter Value
1/8 = shutter value per second of 8

Application of exposure value table

Cameras sometimes fail to measure their light. They say that photographers used to measure the light with their eyes. In fact, their eyes are not the light measuring tool, but guessed by different environments. However, they usually guess well.

Beach and snow scenes under significant shadows during the day = ev16
Significant shadows on sunny days = ev15
Cloudy and sunny day shadows are not obvious = ev14
Cloudy Day with bright white clouds (no shadow) = ev13
Cloudy day with no bright white clouds (no shadow) = ev12
Sunny day under shadow = ev12

Outdoor rainbow blue sky cloudification = ev15
Outdoor rainbow gray sky wooyun = ev14
Minutes before sunset = EV12-14
Sunset = ev12
Minutes behind every day = EV 9-11
