CHAPTER 5: CHOOSING YOUR
CONTRAST
Prodigi allows you to view documents,
pictures and objects in 3 types of contrast:
color, positive or negative. For documents
that contain text, a 4
th
type of contrast can be
used: Diamond Edge™. Positive, negative,
and Diamond Edge™ contrasts are
enhanced; they are meant to enhance the
original color of a document or object to
facilitate your visual experience.
Color contrast is useful if you want to view
documents, objects, and photographs in their
original color.
Positive contrast shows text and images in 2
colors according to your selected color
combination, the default combination being
Black on White. This is a practical way to
view text in the best color combination for
your vision.
Negative contrast shows text and images in
reversed contrast as compared to your
selected color combination. For example, if
Page 25
your combination is Black on White, negative
contrast will show text and images in White
on Black. This is useful if you wish to reverse
the contrast of a text that contains different
contrasts.
Diamond Edge™ contrast combines the best
of both worlds; it shows Diamond Edge
Text™ in your selected color combination
and images in their original color. This allows
you to magnify text indefinitely without
compromising its quality in the best color
combination for your vision, while viewing
images in their original color on the same
page.
To toggle between the different contrasts,
press and hold the Back button to access the
Settings, scroll down by panning upwards to
select Contrast, and tap to choose a contrast.
