Set the white balance
You can adjust the white balance of a photo to reflect the lighting conditions under which it was taken—daylight, tungsten, flash, and so on.
You can either choose a white balance preset option or click a photo area that you want to specify as a neutral color. Lightroom adjusts the white balance setting, and then you can fine-tune it using the sliders provided.
Choose a white balance preset option
Specify a neutral area in the photo
- In the Basic panel of the Develop module, click the White Balance Selector tool to select it, or press the W key. Move the White Balance Selector into an area of the photo that should be a neutral light gray. Avoid spectral highlights or areas that are 100% white. Set options in the toolbar as needed. Auto Dismiss Sets the White Balance Selector tool to dismiss automatically after clicking only once in the photo.
Show Loupe Displays a close-up view and the RGB values of a sampling of pixels under the White Balance Selector.
Scale Slider Zooms the close-up view in the Loupe.
Done Dismisses the White Balance Selector tool, and the pointer changes to the Hand or Zoom-in tool by default.
When you find an appropriate area, click it.
The Temp and Tint sliders in the Basic panel adjust to make the selected color neutral, if possible.
Fine-tune the white balance using the Temp and Tint controls
In the Basic panel of the Develop module,
adjust the Temp and Tint sliders. Temp Fine-tunes the white balance using the Kelvin color temperature scale. Move the slider to the left to make the photo appear cooler, and right to warm the photo colors.
You can also set a specific Kelvin value in the Temp text box to match the color of the ambient light. Click the current value to select the text box and enter a new value. For example, photographic tungsten lights are often balanced at 3200 Kelvin. If you shoot under photo tungsten lights and set the image temperature to 3200, your photos should appear color balanced.
One of the benefits of working with raw files is that you can adjust the color temperature as if you were changing a setting in a camera during capture, allowing a broad range of settings. When working with JPEG, TIFF, and PSD files, you work in a scale of -100 to 100 rather than the Kelvin scale. Non-raw files such as JPEG or TIFF include the temperate setting in the file, so the temperate scale is more limited.
Tint Fine-tunes the white balance to compensate for a green or magenta tint. Move the slider to the left (negative values) to add green to the photo; move it to the right (positive values) to add magenta.
If you see a green or magenta color cast in the shadow areas after adjusting the temperature and tint, try removing it by adjusting the Shadows Tint slider in the Camera Calibration panel. Source: help.adobe.com
