Colour correction and colour grading in video
To give a professional look to your shot footage, some amount of colour (color for Americans) correction and colour grading is important. Though quite a few people use both the terms, colour correction and colour grading interchangeably - they are in fact, two different processes altogether. So what is the difference between colour correction and colour grading in video, film or photography?
Image 1: Footage as captured. Flat and raw. Notice the low contrast and saturation.
Colour correction is the process by which you ensure that all the shots in your film or video have the right white balance, contrast and tone in every scene so that there is no major visual jump in between shots and scenes and they look like a part of the same production and not different shots assembled from different sources. The final outcome of the colour correction process is to often make the shot footage look as natural or real as possible - more so because more and more people and cameras shoot in a "flat" picture style which might not look very pleasing to the eye. In one sense, colour correction is an essential part of preparing your footage for colour grading.

Colour grading is applied after colour correction and is referred to the process of giving different colour tones and hues to your footage so that it creatively conveys the theme on which the film or video is based. It is largely a creative process where the creator of the piece decides that his film will look better with such a tonality. Colour grading is more about conveying a mood that suits the film and it involves manipulation of highlights, midtones and shadows to give the entire footage a different tone altogether.
