Want to capture
the world’s true colors?
It’s a breakthrough. It’s unique.
It’s an image sensor with all
the amazing color sensitivity of film.
The conventional image sensors used
in almost all digital SLR cameras so far,
can only detect light intensity:
they miss a lot of color information.
Using a color filter, they fill in the gaps
in their color perception by means of
complex computations, interpolating
colors that aren't really there, and
artificially synthesizing hypothetical
hues. In short, most digital cameras
use a color synthesis mechanism that is
fundamentally flawed.
Did you realize this is why digital
cameras don't have the descriptive
capacity of film cameras?
Why digital cameras are always
strong on sharp definition,
but weak on color sensitivity?
Using the Foveon X3®, a unique and
groundbreaking direct image sensor,
the SD14 is about to turn this
conventional thinking on its head.
The Foveon X3® has a radically
innovative mechanism in the form of
three vertically-stacked layers of color-
sensing pixels — one for red light,
one for green and one for blue — just
like the three layers of emulsion in
photographic film. These three layers
capture absolutely all the color directly,
and record it faithfully.
Captured without loss or distortion
of colors, the data delivers an
astonishingly vivid feel, far beyond the
image quality you would expect from
the pixel count. This means amazingly
natural color, satisfyingly rich texture
and image quality with a purity that has
to be seen to be believed.

It’s the only camera truly faithful
to the colors of nature.

Foveon X3®
Most digital cameras use Bayer-
filter image sensors, in which red,
green and blue sensor elements
are arranged in a mosaic pattern.
Their basic drawback is that each
pixel only captures a third of the
color data, and the remaining two
thirds have to be extrapolated
using complex algorithms.
Interpolation using a color filter and
artificial color synthesis results in a
loss of detail, so in the conventional
system, no matter how many
extra pixels it has, a conventional
camera can only record artificially-
generated images by calculating
colors that weren’t even there in
the first place.
The SD14, however, uses the
Foveon X3® direct image sensor,
which relies on a full-color
capture system that takes in the
full complement of color data.
This radically-innovative process
delivers genuine high image quality
without any compromise at all.

direct image sensor.
The
Foveon X3® Sensor
Only the FOVEON X3® image sensor
captures 100% of the R(red), G(green), and
B (blue) light at every pixel location.
The
Bayer-filter Image Sensor
A conventional Bayer-filter image sensors
capture only 25% of the R(red) and B(blue),
and just 50% of the G(green).
