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 center of an image.
If you see light vertical lines on the
scanned image, the TPU
calibration area may contain dirt
or dust. Clean the calibration area
with a lint free cloth.
