What is changing gamma of images?
  • Gamma correction, also known as gamma encoding, is a technique used in image processing to adjust the brightness and contrast of an image. The gamma value, also known as the gamma correction factor, controls the relationship between the input and output of an image.
  • The gamma value of an image controls the brightness of the mid-tones, or the tones in the middle of the brightness range of an image. A lower gamma value will result in a darker image, while a higher gamma value will result in a brighter image.
  • Gamma correction can be used to adjust the overall brightness and contrast of an image, and to correct for the non-linear response of certain displays and printers. It can also be used to adjust the brightness of an image to match the viewing conditions of the image. For example, adjusting the gamma of an image to match the viewing conditions of a room with low light.
