Hello! Today, let’s talk about the importance of light source color temperature and white balance in photography.

Understanding Color Temperature and White Balance

Each light source has a specific color temperature. Here are some common examples:

  • 1600K: Sunrise and sunset
  • 1800K: Candlelight
  • 2800K: Tungsten bulb (household light bulb)
  • 3200K: Fluorescent light
  • 5000K: Daylight, often used as the standard for professional light boxes in photography and art
  • 5200K: Bright midday sunlight
  • 5500K: General daylight, electronic flash
  • 6000K: Slightly overcast weather
  • 6500K: Heavily overcast weather
  • 8000K: Foggy weather

Color temperature refers to the light source, while white balance is a camera setting. Setting the correct white balance ensures the accurate reproduction of the colors of the subject being photographed.

Adjusting White Balance

To adjust the white balance accurately, refer to the approximate values listed above and make small adjustments as needed. Alternatively, shoot in RAW format and adjust the white balance during post-processing.

When photos appear too yellow or too blue, it’s likely due to incorrect white balance settings. If the white balance setting is higher than the actual color temperature, the photo will have a yellowish tint. Conversely, if the setting is lower, the photo will appear bluish.

Creative Use of White Balance

You can also intentionally set the white balance higher or lower to achieve creative effects. For example, when shooting cityscapes at night, there are multiple light sources, including building lights, streetlights, and moonlight. It’s challenging to set a unified white balance, so I often use the color tones of the white balance for creative purposes rather than striving to reproduce the original colors.

Using a lower color temperature (3000K) can highlight a modern, futuristic, and cool feeling in urban scenes.

My Approach to White Balance in Food Photography

As a food photographer, I mainly shoot dishes like hotpots, meats, and stir-fries. Generally, I use a higher color temperature of around 5200K or more to accentuate the warm ambiance of the food. Unless there’s a special request or a need to capture a more stylized scene, like cocktails at a bar, I stick to a higher color temperature.

The common backgrounds for food photography, often wooden surfaces, look more natural with higher color temperatures (blue-toned wood would look strange, right?).

Naturally, there are few blue-toned foods in the natural world. Hence, as a food photographer, it’s essential to use a higher color temperature for shooting.

Additionally, since post-processing may require significant adjustments to meet client demands, shooting in RAW format and adjusting the white balance during editing is a crucial step!

By creatively using white balance, you can easily change the mood and tone of your photos. Give it a try and practice adjusting your white balance for different effects!
