White balance and colour temperature, from candle to shade

For anyone who shoots in mixed light. Checked against CullTone on 20 Oct 2026.

Every light source has a colour. Your eye adjusts to it within seconds, so a tungsten-lit hall looks white to the guests. The camera doesn't adjust on its own. White balance is the setting that tells it what "white" should look like under the light you're standing in.

Why the camera's numbers run backwards

On the scale above, higher numbers look bluer. Then you set your camera to 8,000 K and the picture turns warmer. Both are right. The light scale describes the light; the camera setting describes the light you are telling it to cancel. Tell it "this light is 8,000 K, very blue" and it adds orange to compensate. In daylight, that makes the frame warm.

So: if the picture is too blue, raise the number. Too orange, lower it. Once that clicks, it stays clicked.

Tint is the other half

Temperature runs from blue to amber. Tint runs from green to magenta, and it is where cheap fluorescent tubes and some LED panels do their damage, leaving faces faintly green. Fix tint on skin, not on a white wall. A wall can be painted any off-white; a face that reads green is wrong whatever the wall says.

In a RAW file, white balance is only a note

A RAW records what the sensor saw and stores your white balance setting beside it as an instruction for later. Change it in the edit and nothing is lost. A JPEG from the camera has the white balance baked into its pixels, and moving it far afterwards costs colour, most visibly in skin and skies.

That is the honest case for auto white balance on a busy wedding day. Shoot RAW, let the camera guess, and fix it once per scene in the edit. Setting Kelvin by hand is better when the light is steady for an hour, such as a church ceremony; at a reception that switches between uplights and window light every song, chasing it costs you moments.

Mixed light: choose the faces

A reception might have tungsten chandeliers, a window with blue evening light, and LED uplights in purple. No single setting makes all of it neutral. Pick the light falling on the faces that matter, set white balance for that, and let the rest keep its colour. Purple uplights behind a dance floor are part of the room. A purple face isn't.

When two people in the same frame stand under two kinds of light, a single global fix will always leave one of them off. That frame needs a local adjustment on one face, or a decision about which one the picture is about.

When not to correct at all

Some warmth is the event. Candlelit dinners, sunset portraits, a fireplace in winter: neutralise those and the photo forgets what the evening felt like. The same goes for Indian ceremonies lit by diyas and marigolds, and the yellow of a haldi morning, where the turmeric is the point.

We would go further and say most photographers correct too much. Aim for skin that looks like skin under that light, not skin that looks like it was photographed at noon. CullTone's edits start from your camera's own colour and then adjust exposure and white balance, and the cultural looks keep the marigold, tungsten and diya warmth that a general look would pull out (see the looks).

A quick routine for a wedding day

1. Shoot RAW, on auto white balance unless the light holds steady.
2. At each new location, take one frame of something neutral: a grey card, a white napkin, the groom's shirt.
3. In the edit, set white balance from that frame and copy it to the whole scene.
4. Then look at faces, not the reference. Warm it back up if the moment was warm.

For what happens to skin when the balance is off, read skin tones in every complexion.
