Digital Grain Dissolver
Digital Grain Dissolver reduces the effect of film grain. Grain is a sandy texture that can some-
times be seen in smooth uniform areas of the image such as the sky. Grain is more pronounced
in fast film. The results vary with the film. Scanning time increases.

Set the grain-level slider to the approximate grain level of the film; the index uses an ISO scale
for reference. The actual grain depends on the specific film. Set the processing level with the
slider.
Adjust or move the Digital Grain Dissolver sample area to select the portion of the image to be
used to evaluate the grain processing. Choose a smooth uniform area for the evaluation; skin or
sky are good subjects. Click and drag the center of the area to move it. Click and drag on the
frame to resize.
Click the apply button to preview the effect on the sample area. Every time the Digital-Grain
Dissolver sample area is changed, or the degree of correction is adjusted, click the apply button
to view the results. The sample image can be magnified by clicking the fit-to-window button.
Click the scan button to save the final image. To turn off the Digital Grain Dissolver, click the
Digital Grain Dissolver button again.
