    Adjust brightness and contrast separately

    • Brightness and Contrast are separate controls, each ranging from -100 to 100.
    • Brightness shifts color channels; Contrast changes their distance from the middle of the tonal range.
    • Strong settings can clip highlights or lose shadow detail, while image dimensions stay unchanged.
