YOU CAN MAKE ENTIRE YOUR PHOTO BRIGHTER OR DARKER
The BRIGHTNESS function either increase or decrease the brightness data in all pixels.
1. BRIGHTEN YOUR PHOTO
Please see the photos below. I increased BRIGHTNESS. Please compare dark area, bright area and other area. You can see all areas are brighter than the original photo.

This is an another example.


I increased BRIGHTNESS up to 66.

This is the last example.

2. DARKEN YOUR PHOTO
Next, I decrease BRIGHTNESS. Please see the photos below. You can see all areas become darker.

This is an another example. Darkness evokes fear.
