38 BASIC IMAGE PROCESSING
Auto Dust Brush
Original image With Auto Dust Brush processing
The Auto Dust Brush reduces the visibility of fine dust particles on
the film surface that cannot be removed with a brush or blower; all
visible dust should be removed from the film, see handling film on
page 18. The scanning time increases with the use of the Auto Dust
Brush. This function cannot be used with 16-bit linear color depth.
See page 11 for memory requirements.
Click the Auto Dust Brush button to
activate the function; the dust removal
processing is done at the final scan
and is not applied to the prescan
image. To cancel the Auto Dust Brush,
click the Auto Dust Brush button again.
The Auto Dust Brush effect varies with the images and exposure control settings. The
dust-removal effect is greater at high input resolutions. The retouching level can be
changed in the preferences dialog box, see below. The Auto Dust Brush plug-in allows
more control over a scanned image, see page 84.
