DIMAGE SCAN DUAL III UTILITY – IMAGE PROCESSING

A short guide to tone curve corrections

Image processing is a highly specialized and difficult field that takes years of practice to master. This basic guide to using tone curves covers a few simple procedures to improve your pictures. For more about digital-image processing, consult your local book dealer about self-help guides on this subject.

Bringing out detail in the shadows

This is a simple technique to make a subject hidden in the shadows brighter. Unlike the brightness level control (p. 70), this method of correction will not loose details in the highlight areas of the image.

With the RGB channel selected, place the smooth-curve cursor on the center of the curve. Click and drag the curve up. Look at the displayed image to judge the result. The adjustment can be very small and still have a significant impact on the image. Moving the tone curve down will make the image darker.

For most home use where the image is displayed on a monitor or printed with a small printer, sRGB color space is adequate. Other color spaces have been included for professional and technical applications.
