This section covers the advanced image-processing tools in the DiMAGE Scan
Utility. Adjustments to color, contrast, brightness, hue, saturation, sharpness, and film
grain can be made. Functions to view and save image corrections are also available.
The basic image-processing section on pages 22 through 27 should be read before
continuing.

The RGB display will show the color values
for any point on the image; the first num-
bers of each color channel indicate the orig-
inal value of the prescanned image followed
by the current value with any changes made
through processing. Simply place the
mouse pointer on the image area to see the
RGB values of that point. Pressing the shift
key (Windows) or command key
(Macintosh) will display the CMY values.
Digital ROC (Reconstruction of Color) can restore the faded color of old film, see
page 2. The results with Digital ROC vary with the condition of the film.
Digital ROC - Reconstruction Of Color
When Digital ROC is used, the prescan also makes the final scan. When the final
scan is made, the image data is simply processed and saved. While the final scan is
relatively fast, the prescans require more time. Because the final scan and prescan
are made at the same time, always preform the prescan with the autofocus-at-scan
function active in the preferences box (p. 28), or with point AF (p. 34) or manual
focus (p. 35). To turn off Digital ROC, click the Digital-ROC button again.
Digital ROC cannot be used with 16-bit linear color depth (p. 28). When Digital ROC
is activated, the auto-expose-for-slides setting in the preferences box, color match-
ing, and the AE lock and AE-area-selection functions are disabled.
Digital ROC cannot be used with traditional silver-halide black and white films.
Special black and white films that are designed to be developed in a C-41 or equiva-
lent color process, Kodak Select Black & White 400, Kodak T400CN, or Ilford XP2
Super, can be processed with the Digital ROC function. These films should be
scanned with the color-negative film-type setting. Results cannot be guarantied with
other types of black and white film.
The undo, redo, and reset-all buttons have no effect with the Digital ICE
3
functions.
