Enhancing Images

The settings that can be adjusted depend on the image quality setting in effect when the photograph was recorded. Photographs taken at an image-quality setting of RAW can be processed to adjust white balance, reduce the effects of dust, perform vignette control, or to alter exposure compensation, image sharpening, tone compensation, color mode, and hue adjustment from the settings in effect at the time the photograph was taken. All images can be processed using the tools in the Curves, Color Balance, LCH Editor, Color Booster, Photo Effects, Unsharp Mask, Noise Reduction, D-Lighting, Red Eye Correction, and Size/Resolution palettes. Images taken with an AF DX 10.5 mm f2.8G fisheye Nikkor lens can also be pro- cessed to reduce distortion.

The Curves Tool and the LCH Editor

The Curves tool controls the distribution of tones in the red, green, and blue channels and in the RGB master channel, and provides visual feedback on the amount of tone information lost through editing. The LCH Editor is a better tool for making fine adjustments to luminosity (brightness), color saturation, and hue; note, however, that changes to these settings may produce results that exceed the dynamic range of the RGB channels.
