A Photoprocessing Engine Designed to Deliver Priceless Images
The brand-new “TRUE II”
image-processing engine
The DP1 offers a specially-designed
image-processing engine called
“TRUE”. For the DP2, we developed
this key technology further, creating
“TRUEII” and it was first incorporated
to the DP2. Applying our exhaustive
knowledge of the image-creation
mechanism of the direct image
sensor, we used a proprietary
algorithm to do full justice to its
uniquely sophisticated 3-D rendering
power, successfully optimizing both
the image-processing time and the
in-camera image processing itself.
Having focused our efforts on
optimizing and recording the pure,
rich signal captured by the sensor,
we were determined that the DP
series would be the only camera fully
able to deliver the optimal image
quality we had pursued throughout
our development of SLRs. The
rich optical signal captured by
the groundbreaking Foveon X3®
direct image sensor needed to be
translated into an information-rich
image. We entrusted that crucial task
to our new, improved “TRUE II”.
JPEG mode: photos
finished the Sigma way
JPEG images captured by the SIGMA
DP are photos finished in what Sigma
considers the most appropriate way.
If you find that the photos you take
in JPEG mode look the way you
intended, then by all means enjoy
the ease and convenience of the
JPEG setting. Your JPEG images are
ready to print – just plug the camera
into your printer – and the image
data files are ready to share with
your friends and family. If you want
email-friendly image files that can
be transferred straight from your
camera, JPEG mode wins hands-
down on convenience.
However, when you create a
JPEG file, the data is subjected to
irreversible compression, which
leaves very little scope for image-
correction afterwards. And here's
the rub: if you only shoot JPEG
mode, you may find it very difficult
to reproduce the photo you saw
in your mind's eye, which is your
own personal sensory experience.
If you've ever used a conventional
compact digital camera that only
has JPEG mode, you'll know how
unsatisfying the results can be.
Unfortunately, it can be extremely
difficult to fully express your artistic
vision using only JPEG images,
which are created using the camera's
automatic settings.
Photo-finishing software
designed to handle RAW files
The SIGMA DP has an X3F mode
(RAW file format) in which all
the image data captured by the
sensor can be recorded without
any significant deterioration in
camera performance. If you want
to do your own hands-on photo-
finishing, then for best results,
we recommend Sigma Photo Pro,
the image-processing software
designed exclusively for these X3F
files. You may think that “RAW data
processing” sounds like something
intimidatingly technical, requiring
high levels of knowledge and skill.
If so, just try Sigma Photo Pro for
yourself, and you'll soon find out
how easy it really can be. Sigma
Photo Pro focuses on only those
functions you really need for artistic
photo-finishing. Its interface is one
