Brightness
Brightness
is the overall lightness of the image. Move the slider left or right to darken
or lighten the image. Adjusting the brightness level adjusts the tone of the pixels, without
changing the true color of the pixels.
Contrast
Contrast
refers to the differences between the light and dark portions in the image. Move
the slider left or right to decrease or increase the contrast levels. Increasing the contrast
level emphasizes the difference between the lighter and darker portions of the image,
decreasing the contrast de-emphasizes that difference.
