Colour Correction vs. Colour Grading
These two terms are often used interchangeably, albeit incorrectly. Colour correction as the name suggests is fixing/cleaning the original picture i.e. remove colour casts, relighting, white balance while Colour Grading is applying a look and feel to the picture.
