Digital Grain Dissolver

Digital GEM reduces the effect of film grain. Grain is a sandy texture that can sometimes 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- GEM 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.
