different shades of gray in an image. In 8-bit images, there can be up to 256 shades of gray. Every pixel of a grayscale
image has a brightness value ranging from 0 (black) to 255 (white). In 16-bit and 32-bit images, the number of shades
in an image is much greater than in 8-bit images.
Inverts the colors in an image. When you invert an image, the brightness value of each pixel in the
Invert Color

with a value of 255 is changed to 0, and a pixel with a value of 5, to 250.
