Make it right, then make it feel like something

Two different jobs that get mixed together

Colour work is two separate operations and doing them in the wrong order wastes most of an evening.

Correction is making the shot right: neutral whites, sensible exposure, matching shots that were filmed minutes apart under drifting light so they belong in the same scene.

Grading is making it feel like something: teal shadows, warm skin, crushed blacks, a bleached daylight look.

Correction first, always, and here is the mechanism. A grade is a set of adjustments built on assumptions about where mid-grey sits, where skin sits and where black sits. If shot one is 600 K too warm and a stop underexposed, and shot two is neutral, the identical grade lands on two different starting points and produces two different results. You end up regrading every shot from scratch and the scene still does not match. Correct first so all your shots agree with each other, then one grade travels across all of them.

Your eyes are lying and the scopes are not

Two things make eyeballing colour unreliable, and neither is about skill.

Chromatic adaptation: look at a warm image for twenty seconds and your visual system rebalances until it looks neutral. Grade for ten minutes and you will keep pushing further in the same direction without noticing. Then you look at it the next morning and it is orange.

And your viewing conditions lie. An uncalibrated laptop panel, a room lit by a yellow bulb, a phone with automatic warmth at night — each shifts what you are seeing by more than the adjustments you are making.

So use the scopes. They are in Resolve's free version, in Kdenlive, and in Premiere.

• Waveform for exposure. The vertical axis is brightness. You can see instantly whether highlights are clipping at the top or shadows are crushed against the bottom.
• RGB Parade for white balance. Three waveforms side by side, red then green then blue. In a neutral shot the bottoms should line up and the tops should line up. If blue sits higher at the bottom than red and green, your shadows are blue — pull blue lift down until the bases align. This one reading fixes most white-balance problems in about fifteen seconds.
• Vectorscope for saturation and hue. There is a diagonal reference line running toward orange, roughly eleven degrees off vertical, and human skin of every colour falls close to it. If your faces are pointing well off that line, something is wrong regardless of how the picture feels.

An order of operations that works

1. 1Black point. Bring the darkest part of the image down until it just reaches the bottom of the waveform without crushing detail you want.
2. 2White point. Bring the brightest part up until it approaches the top without clipping.
3. 3Mid-tones. Now set the overall brightness of faces, which is the only exposure the viewer actually judges.
4. 4White balance, using the parade.
5. 5Saturation, last and modestly.

Only then reach for a look.

LUTs are not magic and this is why they disappoint

A LUT — lookup table — maps every input colour to an output colour. Apply a film-emulation LUT to a shot and it can look superb or it can look like a bruise, and the difference is almost never the LUT.

Most cinematic LUTs are built to receive a log image: a flat, grey, desaturated signal from a camera set to record maximum dynamic range. Feed one a normal, already-contrasty image and it applies a second dose of contrast and saturation on top of the first, blowing highlights and blocking shadows. Feed it a shot that has not been corrected and it faithfully amplifies the colour cast.

So: correct first, then apply the LUT, then dial its strength down — most look better at 50 to 70%.

Related, and worth knowing before you buy a camera: log recording only helps if the camera has real 10-bit capture. Log spreads the tonal range thinly so you can redistribute it later. In 8-bit there are only 256 levels per channel to spread, so when you add the contrast back you get visible banding in skies and gradients. Log on an 8-bit phone or entry camera generally costs you more than it gains. Shoot a normal profile, expose it properly, and grade gently.

The washed-out export

You grade a piece, it looks right in the timeline, you export it, and the file looks flat and grey in the player. Almost nobody guesses this correctly the first time.

It is usually a data-level mismatch. Video can be tagged as full range, where 8-bit values run 0 to 255, or video range, where black sits at 16 and white at 235. If a file is encoded as one and interpreted as the other, blacks lift and whites dull, and the whole image looks washed. Nothing is wrong with your grade.

Look for a data levels or range setting in your export dialogue, set it to Auto or Video, and check the result in a different player — VLC is free and honest. If it looks right in VLC and wrong in a browser, the tag is the suspect.

The money rule here is unusually strong

Colour is the one area where the free tool is not a compromise at all. DaVinci Resolve's colour page is what feature films are graded on, and it is in the free version. Nothing about node-based grading, power windows, tracking or scopes is held back. If you are learning grading, you are learning it on the same software the professionals use, at no cost.

Kdenlive and Shotcut have basic colour wheels and curves and will handle a straightforward correction. On a phone, colour work is limited to global adjustments and filters; treat it as correction only.

Take one shot, open the RGB parade, and align the bottoms of the three channels. Do nothing else. Compare before and after.
