Colour processing in the production of
films is now done digitally due to advanced technology. These colour footages
can be fully transformed and become extremely enhanced with just a few simple
steps.
The two main types of colour
manipulation are called colour correction and colour grading and are both used
in different ways to be effective to the viewers.
Colour grading:
Colour grading is a process that
includes multiple changes to the footage which can change the visual tone to a
film. Colour grading is used as a brush over process just like a picture would
be painted for a purpose. These changes include:
- Removing objects
- cinematic looks
- Shot matching
- Shape masks
Colour grading is a much more advanced
and professional process compared to colour correction. Due to it being high
end, it is not used in that many film industry products. So, when the editor of
a product is making it, they must take into account that if they want more
detailed colour profiles, they will have to prepare for longer rendering times.
Colour Correction:
Colour correction on the other hand, is
a singular process that just involves any minor adjustments to an image/video
from its original/raw appearance.
The corrections include:
- Contrast
- White balance
- Exposure
If there are camera mistakes in a
certain footage, colour correction is useful for covering these mistakes. So,
from a professional point of view, you should colour correct your footage
whenever you can so the footage looks significantly improved.
