The contrast adjustment is good method to change the image properties to get a better visual appearance. When contrast is intensified, some principles of human eye perception are considered - the darkness/brightness ratio and saturation increase. As more as contrast is increased, more data are overridden, so the quality of image can't be recovered later.
