A method and apparatus for displaying an image which has a wide dynamic range. Low spatial frequency components of the image are extracted from the image signal and are presented as a color overlay which tints an intensity modulated display of local high spatial frequency image components. In a preferred embodiment, the hue of the color overlay is modulated to indicate whether the local background component is greater than or less than an equilibrium value while the saturation is modulated to indicate the absolute value of the deviation.
