What is brightness and contrast of an image?
Brightness increases the overall lightness of the image—for example, making dark colors lighter and light colors whiter—while contrast adjusts the difference between the darkest and lightest colors. Below is an example of adjustments made to the brightness and contrast of an image.
What is brightness in imaging?
Image brightness (or luminous brightness) is a measure of intensity after the image has been acquired with a digital camera or digitized by an analog-to-digital converter.
Should my brightness and contrast be the same?
Optimal Brightness and Contrast Settings
As a basic rule, regular computer users should aim to have their monitor's brightness match the brightness of their workspace, with the contrast set for optimal readability and minimal eye fatigue.
How does brightness affect contrast?
Brightening an image will increase contrast in dark areas but decrease contrast in bright areas, while darkening the image will have the opposite effect.
