White Balance Explained: Fixing Weird Colors

Why Does My Photo Look Yellow?

I remember returning to my hotel room after an incredible evening photographing the bustling night markets in Southeast Asia. The street food stalls were illuminated by hundreds of hanging incandescent bulbs, casting a beautiful, cinematic glow over the crowds. But when I downloaded my photos onto my laptop, my heart sank. Every single photo was drowning in a sickening, radioactive orange hue. The people looked like they had jaundice, and the delicious food looked unappetizing. I thought my camera's sensor was broken. It wasn't until weeks later that another photographer explained the concept I had completely ignored: White Balance.

Your human eyes are an absolute marvel of biological engineering. When you walk from a sunlit park (which has very blue, cool light) into your living room lit by a cheap lamp (which has very orange, warm light), your brain instantly color-corrects the scene. A white piece of paper looks white outside, and it looks white inside. Your camera's computer is not that smart. It needs to be explicitly told what "white" is supposed to look like under different types of lighting.

The Kelvin Temperature Scale

To understand white balance, you have to understand that light has a physical "temperature," measured in Kelvin (K). This isn't about heat; it's about the color of the light.

Imagine a blacksmith heating a piece of metal in a forge. As it gets hot, it glows a deep, warm orange (around 2,000K to 3,000K). This is the color temperature of candlelight, tungsten lightbulbs, and the golden hour at sunset. As the metal gets hotter, it turns white (around 5,000K to 5,500K), which matches the color of bright, midday sunlight. If the metal gets unimaginably hot, it burns a searing blue (7,000K to 10,000K), which matches the color of light on a heavy, overcast, cloudy day or in deep shade.

When you set your camera's White Balance, you are essentially telling the camera's computer, "Hey, the light hitting this scene is very orange (3,000K). Please add a bunch of digital blue to the photo to cool it down and neutralize the colors so they look natural."

The Danger of Auto White Balance (AWB)

Most beginners leave their camera in Auto White Balance (AWB). Under bright, midday sunlight, AWB does a fantastic job. The camera easily recognizes the standard 5,500K daylight and renders colors perfectly.

However, AWB will absolutely ruin your photos in two specific scenarios: tricky mixed lighting, and moody sunsets. If you are shooting a portrait near a window (blue daylight coming in) but a lamp is turned on inside the room (orange tungsten light), AWB will panic. It doesn't know which light source to neutralize, and you will often end up with a person whose face is orange on one side and sickly blue on the other.

The worst offense of AWB happens at sunset. When the sky explodes into a beautiful array of fiery reds, oranges, and magentas, you want to capture those warm tones. But AWB sees all that orange light and thinks, "Oh no, there is way too much orange here! I need to fix this by adding a massive amount of blue!" The camera actively fights against the sunset, turning your beautiful, warm golden hour photo into a flat, cold, grayish-blue mess.

Taking Control: Manual White Balance Presets

To fix this, you must take your camera out of AWB. Your camera has several built-in presets that are incredibly easy to use. These presets are represented by little icons in your menu:

• Daylight (Sun icon): Sets the camera to ~5200K. Use this outdoors on a clear day.
• Cloudy (Cloud icon): Adds warmth to the photo. Use this on overcast days so your photos don't look overly blue and depressing. This is also a fantastic "cheat code" to use during a sunset; it will force the camera to add extra warm, golden tones to the sky!
• Shade (House with a shadow icon): Adds extreme warmth. Deep shade is very blue, so this preset adds a lot of orange to neutralize it.
• Tungsten/Incandescent (Lightbulb icon): Adds extreme blue. Use this only when shooting indoors under old, warm lightbulbs, or your photos will look like they were dipped in orange paint.
• Fluorescent (Glowing tube icon): Adds magenta. Office fluorescent lights often cast a sickly green hue. This preset adds magenta to counteract the green and make human skin look natural again.

The Ultimate Safety Net: Shooting in RAW

If you are overwhelmed by trying to remember all these Kelvin temperatures and lightbulb icons while you are in the field, there is a magic bullet that completely eliminates the stress of White Balance: shooting in RAW format instead of JPEG.

When you shoot a JPEG, the camera takes the White Balance setting you chose (even if it was wrong), permanently bakes that color adjustment into the pixels, and throws away the rest of the color data. If you accidentally shot a snowy landscape using the Tungsten preset, the snow will be neon blue, and it is almost impossible to fix in editing without destroying the image quality.

When you shoot in RAW, the camera records the pure, raw data from the sensor without baking the White Balance in. You can shoot an entire wedding with the White Balance set completely wrong, open the RAW files on your computer in Lightroom or Photoshop, and change the White Balance perfectly with a single slider, without losing a single pixel of quality. It is the closest thing to a time machine in photography.
