What colour grading does

Colour grading can be hard to value when the useful work is subtle. Ask to see what changed in the footage and why: matching shots, controlling contrast or establishing the intended look.

Correction balances exposure and colour for the intended image. Grading develops the look: where attention goes, what mood the room carries and how the shots belong together. The work can overlap, and both take judgement.

What is a LUT, and why is it not a grade?

A LUT is a preset: a lookup table that shifts every colour in your image to a different colour, all at once, according to a fixed recipe. Drop it on a clip and the whole picture changes in one move.

It is useful, and it is one operation. It knows nothing about your footage. It does not know where your face is, whether your white balance was wrong, whether the background is competing with you or how bright the window was. It applies one fixed recipe, the same answer for every pixel of a given colour, and it never looks at where that pixel sits or what it belongs to.

Use each transform in the colour pipeline it was designed for. A creative LUT cannot replace shot balancing; a technical LUT may be part of getting the footage into the right working or display space.

What sits underneath a real grade?

Several operations running in parallel on the same shot, each doing a job you would struggle to describe to anybody watching. They are meant to be invisible, which is precisely why the work is easy to doubt.

Balance

Getting white to be white and the exposure to sit where it should. This is the foundation and it is the part you can learn. Everything else is unreliable until it is done.

Separating the subject from the background

The wall behind you and your jumper are often close in brightness, so you sink into the room. A grade pulls them apart: the background comes down a little, the subject stays up, and suddenly there is depth in a flat frame.

Masked light that finds the face

A soft mask can brighten part of a subject and follow them through the shot. Use it where the recorded image has room for the adjustment, and check that the treatment does not announce itself.

A vignette too faint to notice

The corners come down a fraction. Attention drifts inwards because the eye goes to brightness. Push it far enough to be visible and it looks like a photograph from decades ago, so the whole skill is in stopping early.

Grain kept in on purpose

Noise reduction can make an image too smooth when pushed too far. Keep enough texture for the intended look; added grain is a creative choice, not a requirement for footage to feel real.

That combination, several operations layered on one shot and built specifically for the brand and the lighting setup rather than pulled off a shelf, is what this studio means by a grade. It is not a preset with a different name on it.

Where should you start with your own footage?

Start with exposure, white balance and matching the shots. Those adjustments give you a clearer basis for deciding what look you want to build.

Set white balance manually before you film so the camera stops guessing. Expose so faces are bright enough without the window behind you blowing out. In editing, adjust so white objects read white rather than blue or orange, and lift the shadows only until you can see detail, not until the image goes flat.

Do those and you will have gained more than any preset gives you. A correctly corrected video with no grade at all looks clean and professional. A graded video built on uncorrected footage looks like a filter.

Is grading worth paying for?

Pay for the problem or look the work needs, rather than for the label.

Start with usable exposure, colour and consistency. A colourist may handle those corrections as part of the grade. Better lighting can also help future shoots, but it does not remove the need to finish footage already recorded.

There is one exception worth knowing. If you are cutting between several cameras, matching them to each other is not decoration, it is repair, and it is worth doing properly even when nothing else is. A mismatch between angles is the colour fault an ordinary viewer is most likely to notice.

Before you pay for a grade

Watch three of your videos. Does the subject read clearly, do adjacent shots match and does the image carry the mood you want? Use the answers to brief a short before-and-after sample. A face does not need to be the brightest object in every composition.

Sources and evidence

What here is established colour management and what is our own method.

What is established. A LUT, as the industry colour-management framework ACES documents it, is a defined technical object: a lookup table that maps one set of colour values to another according to a fixed recipe, indexed by colour value rather than by position in the frame. That is the basis for treating it as one operation rather than a grade. Separating a subject from a background by luminance, following a face with a masked light, holding a vignette below the point of being consciously seen and choosing how much grain to keep are craft decisions this studio makes by eye and by testing against real footage, not findings drawn from a standard.

Our method. Correcting before anything else, and building a grade from several small, deliberately invisible operations rather than a single preset, is the practice here.
