Which adjustment is commonly used to adjust the tonal range by redistributing brightness values?

• A. Levels
• B. Exposure
• C. Brightness/Contrast
• D. Colors

Answer: (A)

Adjusting the tonal range by redistributing brightness values is best done with Levels. Levels works on the image’s histogram and lets you set the black point, white point, and midtones. Moving the black point inward deepens shadows; moving the white point outward brightens highlights; adjusting the middle slider changes the gamma to shift midtones. This directly reshapes how brightness values are spread across the image, expanding or compressing parts of the tonal range and reducing clipping in darks or lights. By contrast, Exposure moves all brightness values up or down uniformly, which doesn’t redistribute the relative differences between tones. Brightness/Contrast changes overall brightness and contrast without rebalancing the tonal distribution, and Colors affects color channels rather than the brightness distribution.
