How Smoked Glass works with image enhancement

When the Smoked Glass feature is enabled, it becomes
linked with the functions of a scan frame and signficantly
impacts the way image-enhancement controls and other
settings (such as resolution) are seen. Details follow.
• If you have smoked glass on, a scan frame defined, and
set image-enhancement and other controls (such as
changing brightness, applying a filter, or changing
resolution), the enhancements are applied to the scan
frame alone.
This means that the part within the scan frame may
change in appearance (as it now has different settings),
but because smoked glass is on, the rest of the image
hidden behind the smoked glass remains unaffected.

• If you have smoked glass off, a scan frame defined, and
set image-enhancement and other controls, the enhance-
ments are still applied to the scan frame alone. But
because smoked glass is turned off, it appears that the
whole image has been altered. This is not the case, as
only the scan frame is affected.
