Setting white balance by hand means telling your camera what color the light is, so a white wall looks white instead of orange or blue. You can do it with a neutral target, a Kelvin number, or a built-in preset. The steps below take only a minute once you know them.
Why automatic white balance sometimes fails
Every light source has a color. Candle flame and household bulbs lean warm and orange, open shade leans cool and blue, and midday sun sits roughly in the middle. Automatic modes guess, and they guess wrong when a frame is dominated by one color, such as a green lawn or a red curtain.
Manual control gives you the same result from one frame to the next, which matters when you shoot a series that must match.
Method one: a custom setting from a neutral target
- Place a gray card or a plain white sheet of paper in the same light that falls on your subject.
- Fill the frame with the card. Focus does not need to be sharp.
- Take one exposure, making sure it is not too dark or too bright.
- Open the white balance menu and choose the custom or measure option, then select the frame you just took.
- Switch white balance to the custom slot and shoot your scene.
Redo this whenever the light changes, for example when a cloud covers the sun or you move to another room.
Method two: dial in a Kelvin value
Most cameras let you type a color temperature directly. Lower numbers make the image bluer, higher numbers make it warmer. These are common ranges, and you adjust by eye:
| Light | Approximate Kelvin |
|---|---|
| Candlelight | 1800 to 2000 |
| Household bulbs | 2700 to 3200 |
| Morning or late afternoon sun | 4000 to 5000 |
| Midday daylight | 5200 to 5600 |
| Cloudy sky | 6000 to 6500 |
| Open shade | 7000 to 8000 |
Look at the screen after one test shot. If whites look yellow, lower the number. If they look blue, raise it.
Method three: presets and fine tuning
Presets such as daylight, cloudy, shade and tungsten are shortcuts for typical Kelvin values. They work well when the light matches the label. If the result is close but not perfect, use the green-magenta shift, which corrects the tint that fluorescent and LED lamps often add.
- Shoot raw if you can; the setting can then be changed later without loss.
- Keep a gray card in your bag for tricky mixed light.
- Do not trust a bright screen alone; check your histogram and a known neutral object.
FAQ
Do I need a gray card?
No. A clean sheet of plain white paper works for most situations, though a proper gray card is more consistent because it is made to be neutral.
Can I fix white balance after the shot?
Yes, easily in raw files and to a lesser degree in JPEG files. Getting it right in camera still saves editing time and gives cleaner skin tones.
The Short Version
Show the camera something neutral in the same light as your subject, or type in a Kelvin value that fits the light, then fine tune by eye. Recheck whenever the light changes, and shoot raw for extra flexibility.
