In post processing, such as in lightroom, you can refine your picture and get rid of grain and color irregularities due to your specific camera's imaging characteristics and ability to handle higher ISO's.
Do you see in the wings and the backs of the ducks there are red/pink colors?...
they don't belong there and are the result of the particular camera/lens that is being used.
