DIGITAL GEM
Digital GEM (Grain Equalisation and Management) reduces the effect of grain in colour film. Grain is
a sandy texture that can sometimes be seen smooth uniform areas of the image, such as the sky.
Grain is more pronounced in fast film.
Digital GEM cannot be used with traditional black and white films. The Digital-GEM function can be
used with special black and white films that are designed to be developed in a C-41 or equivalent
colour process: Kodak Select Black & White 400, Kodak T400CN, and Ilford: XP2 Super. These films
should be scanned with the colour-negative film-type setting. Results cannot be guarantied with
other types of black and white film.
1 Click the Digital-GEM button in the main window.
• The Digital-GEM tab is activated.
• Each time the Digital GEM button is pressed, the
prescan image is deleted and another prescan
needs to be made.
2 Make a prescan of the image to be
processed.
• When Digital GEM 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 perform the prescan with the autofocus-at-scan
function active in the preferences box (see page 34), or with point AF or manual
focus (see page 49 – 50).
3 Set the input resolution of the image in the scan-setting window (see
page 74).
• The effect of image grain is related to the input resolution.
4 Click the Digital-GEM tab.
• The Digital-GEM window appears.
5 Adjust the Digital-GEM slider or enter the
Digital-GEM correction value
directly in the text box to set
the degree of correction.
• Values from 0 to 100 can be set.
The larger the value, the greater the
correction.
