ADVANCED IMAGE PROCESSING

More image-processing tools

This section covers the advanced image-
processing tools in the DiMAGE Scan Utility as
well as functions to view and save image
corrections. The basic image-processing section
on pages 22 through 29 should be read before
continuing.
Unsharp-mask button (p. 58)
Selective-color button (p. 57)
Hue, saturation, and lightness button (p. 56)
Tone curve/histogram button (p. 48)
The RGB display will show the color values
for any point on the image; the first numbers
of each color channel indicate the original
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

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.
Original image
Click the Digital-ROC button to activate
the function; the current prescan image
will be deleted. Press the prescan
button to view the results.
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. 30), or with point AF (p. 36) or manual focus
(p. 37). To turn off Digital ROC, click the Digital-ROC button again.
Digital ROC cannot be used with 16-bit linear color depth (p. 30). When Digital ROC
is activated, the auto-expose-for-slides setting in the preferences box, color matching,
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 equivalent 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
