Adjust Image Levels
See how to adjust image levels.
You use the Levels adjustment to correct the tonal range and color balance of an image by adjusting intensity levels of image shadows, midtones, and highlights. The Levels histogram is a visual guide for adjusting the image key tones.
How to read a histogram
A histogram illustrates how pixels in an image are distributed by graphing the number of pixels at each color intensity level. The histogram shows detail in the shadows (shown in the left part of the histogram), midtones (shown in the middle), and highlights (shown in the right part) A histogram can help you determine whether an image has enough detail to make a good correction.
The histogram also gives a quick picture of the tonal range of the image, or the image key type. A low-key image has detail concentrated in the shadows. A high-key image has detail concentrated in the highlights. And, an average-key image has detail concentrated in the midtones. An image with full tonal range has some pixels in all areas. Identifying the tonal range helps determine appropriate tonal corrections.

The Histogram panel offers many options for viewing tonal and color information about an image. By default, the histogram displays the tonal range of the entire image. To display histogram data for a portion of the image, first select that portion.

Adjust Image Curves
The Curves Tool usually be used to improve color tones in a photo by adjusting highlights, midtones, and shadows in each color channel.

Adjusting color curves in an image:
- In the Editor, open an image.
- To adjust a specific image area or layer, select it with one of the selection tools. (If no selection is made, the adjustment applies to the entire image.)
