How to Adjust White Using the Histogram in Lightroom
Adobe's Lightroom application enables users to both manage and edit large directories of images. The Histogram window provides users with a view of the current image's color dispersion. You can get an idea of how much of the image is composed of dark and light colors, and you can even find out if part of your image's color spectrum has been clipped. And if you feel that the brightest whites in your image are too dull or too strong, you can use Lightroom's Histogram to adjust the white levels in your images.

1
Launch Lightroom. Click on the program's "File" heading, and then select the "Open" option from the context menu that appears beneath the heading. Locate the image you wish to work with, using the file explorer window that appears.

2
Review the data in the Histogram window. If the color data spikes at the right side of the Histogram, then some of your image's lighter colors have been clipped and will need to be expanded to reveal whiter color.

Click on the arrow on the Histogram's left side to reveal the image's clipped white areas -- the clipped areas will be highlighted red. If your image's color data doesn't spike on the right side of the Histogram's spectrum or you'd like to decrease the white levels in your image, omit this step.

Drag the Histogram's "Exposure" and "Recovery" sliders to the left to expand your image's color spectrum and make more room for brighter colors -- the red clipped areas of the images will turn white as you raise the sliders. To decrease the brighter colors of your image, simply drag the right side of the Histogram's color data towards the left.
