Auto Dust Brush – Removing the effect of dust

The Auto Dust Brush reduces the visibility of fine dust particles on the film surface that cannot be removed with a brush or blower. Auto Dust Brush processing is applied to all the images in the holder. The scanning time increases with the use of the Auto Dust Brush. This function cannot be used with 16-bit linear color depth (p. 45).

Before using the Auto Dust Brush, remove all visible dust from the film, see handling film on page

20.Select the autofocus-at-scan option in the preference window (p. 45), or adjust the focus with point AF or manual focus (p. 52). The degree of retouching can be adjusted in the preference win- dow.

The Auto Dust Brush effect varies with the images and exposure control settings. Image details may affect the processing; make multiple scans at different degrees of retouching. The dust- removal effect is greater at high input resolutions.
