Color Correction and Color Grading

Colour correction and colour grading is critical when you shoot a film. It can enhance the atmosphere that you want for your images.

People’s eyes are automatic machine, it can change the colour correction and colour grading by itself, no matter it is cool light or warm light, in doors or out doors. White is always white, black is always black. However, camera cannot do it like the human’s eyes. White can be blueish white and yellowish white through the environment. So we need to set that point, in order to get images which we want.

 

In the process of filming, the quality of the sun is going to change through out of the day. In order to make the final images look like happens at the same time, so we need colour grading, otherwise it looks very strange.

 

Another function is to use colour grading to create an atmosphere, to make it looks more real. For example, if you want to make your story that happened in a warm summer, you need set the warm colour, so that the audience can have the sun feel. However, if that happened at cold raining day, you need to set cool light, to let the audience feel cold and wet.
