Each of the cases(Brightness , Hue , Saturation..etc) are calling some other functions can some one please explain to me how they are doing the required process. Which algorithm or how the brightness or hue or saturation actually changing in this following application. They are in the function viewDidLoad in the file ViewController.m.
