White Balance Explained: Getting Color Right

Color in a photo is relative. Your eyes adapt instantly, so a white shirt looks white under a warm lamp or a blue sky. The camera does not adapt on its own, so it has to be told what white is. That setting is white balance, and getting it wrong is why so many indoor photos come out orange.

Color temperature and Kelvin

Light has a color temperature measured in kelvin (K). Low numbers are warm and orange, high numbers are cool and blue, which feels backwards until you stop thinking of it as hot and cold. A candle is around 1900K, a tungsten bulb around 3200K, midday sun around 5500K, and open shade up around 7500K. White balance shifts the image the opposite way to cancel the cast: under a warm 3200K bulb, the camera adds blue to bring white back to neutral.

Auto, presets, and Kelvin

Auto white balance reads the scene and guesses, and modern cameras guess well in even light. It drifts in mixed or strongly colored light, which is the case for mixed and artificial light. When auto wanders, take control:

• Presets (daylight, cloudy, shade, tungsten, fluorescent) lock a fixed correction. Cloudy and shade warm the image up, which is often flattering.
• Kelvin lets you dial the exact number. Higher K warms the image, lower K cools it. This is the most precise and the most consistent across a series.
• Custom uses a gray card or white sheet you photograph in the actual light, the most accurate option for critical color.

When to break neutral on purpose

Correct is not always the goal. Golden hour looks better left warm, not neutralized into gray. A cold blue cast can suit a winter or night scene. Neutral is the safe default; deliberate warmth or coolness is a creative choice, and the readout you already know from the exposure triangle does not change, only the color does.

Where this fits

White balance is the color half of exposure. Pair it with shooting in different light to read the color of the light you are in, and with portrait photography, where true skin tone matters more than almost anything else.

What white balance should I use?

Auto for everyday shooting in even light. Switch to a preset or a Kelvin value when the light is colored or mixed, or when you need consistent color across many frames. Shooting raw lets you correct any of it later.

Why are my indoor photos orange?

Household bulbs are warm, around 2700K to 3200K, and auto white balance often under-corrects them. Set the tungsten preset or dial a lower Kelvin value, or shoot raw and fix the color in editing.
