I agree. Color correction refered to the overall image. To save effort i'll often apply color filters over the entire image to better blend the face.I think most people don't know the meaning of blending. Blending means matching the color of face with the colour of the body. So in my opinion face blending must be more goid for the all fake creaters. Plz don't get offened if I said something wrong by not knowing . Am just putting opinion.
Thank you
