Image adjustment refers to the process of modifying the visual characteristics of a digital image. This can include altering aspects such as brightness, contrast, saturation, hue, and color balance. The goal of image adjustment is often to improve the aesthetic appeal of an image, correct technical flaws, or prepare it for specific applications. Software applications ranging from simple photo viewers to advanced professional editing tools offer a variety of adjustment options.

Brightness and contrast adjustments directly affect the overall lightness and the range between the darkest and brightest areas of an image, respectively. Saturation controls the intensity of colors, making them appear more vivid or muted. Hue shifts the dominant color tones within an image, while color balance allows for fine-tuning the proportions of red, green, and blue light. Other common adjustments include sharpness, which enhances edge definition, and exposure, which controls the amount of light captured. These adjustments are fundamental techniques in digital photography and graphic design, enabling users to achieve desired visual outcomes.
