The scanner perceives the film
guide's frame as white, which
alters the exposure of the
scanning area and makes the
preview appear darker. To see
the correct colors, do a zoom
preview on an area toward the

If you see light vertical lines on

calibration area may contain
dirt or dust. Clean the
calibration area with a lint free
cloth.
