Colour grading is altering a films colour. Colour grading is producing a different ‘feel’ and ‘look’ to something and at the same time it’s a colour correction.
Colour correction is generally one of the last steps taken to finish an edit in any post-production workflow. It is an online editing.
Sometimes we can put filters on lenses but once it’s shot it is permanent. That’s why it is easier to do in the post-production stage and in case we don’t like it to change it or remove completely.
When the movie ‘Oh Brother Where Art Thou’ was made by Coen Brothers, they digitized the movie film, which made it possible to manipulate the colour within each scene.
For example, in movie ‘Matrix’, different colours of the scenes were used between Matrix and real world.
It seemed to be revolutionary in the past, but now it is a standard practice.
Not always the rule ‘The more the better’ is applicable as it can ruin the whole feel of the film. Colour grading should be used a correction first and then changing the look.
Colour grading is especially helpful when the same scene were shot on different days with different weather. With the use of colour level and effects we can make them all look similar.
Stages of colour grading:
- Correcting errors in colour balance and exposure
- Making sure that key elements look the way they should
- Balancing all the shots in a scene to match
- Creating contrast
- Achieving a ‘look’
Contrast is the difference between the darkest and brightest tonal values within the image.
