Here are a few images that accurately reflect the abilities
of any given camera model. The images are altered only in
terms of size and sharpness after reduction and by the JPEG
compression used. Unless otherwise mentioned, assume that
any marbling or artifacts visible in the images are due to
the compression required to display them here. We feel however,
that they still faithfully represent the results we experienced.
STILL LIFE PHOTO
This subject is photographed in a room that has
a mix of fluorescent and incandescent light, but which is not
brightly lit. The camera's flash is used to add fill light.
The backdrop is 1.95 m (6.5 ft) from the camera.
The advantage of having an 8 megapixel to record an image comes through
clearly with this test shot. Even in wide angle, the F828 captures a superb
level of detail. For example, the inscription around the lens of the cameras
are almost readable.

ZOOM PHOTO
The intent with this photo is to test the sharpness of the image
at the zoom's maximum setting, with the camera remaining at the
same distance as in the preceding photo.
When the 8 megapixel resolution of the F828 is combined with
its 200mm equivalent zoom the result is a sharp and extremely
detailed image.
Whether in wide angle, or at the telephoto setting, the pop-up
flash of the F828 is able to light the subject very well up
to 4m (13 ft).

A note of caution however: when the
flash is used at the widest angle over a short distance, the
lens can cause a shadow in the lower part of the frame.

In macro mode the F828 has a
minimum focus distance of 2cm (0.78 inch) from the front element
of the lens when the lens is at the wide angle setting. At this
distance the field of view is approximately 5.7 cm (2.22 in),
but photos show quite a bit of barrel distortion.
Zooming in and backing up from the subject produces much better results;
and if the aperture priority mode is used and the aperture is set to f8,
the depth of field of the macro mode can be increased substantially.
BUILDING PHOTO
This image is our outdoor test. The architecture
of the building, in particular the angled girders, immediately
show the presence of jaggies. The shadowed entrance can also
often reveal the quality of the exposure.
These outdoor shots of the building are captured close to the Winter solstice,
at around noon. At this season in Vancouver, just above the 49th parallel,
the sun is quite low in the sky, even at noon. The light that bathes the
building is low and harsh, and provide a real challenge to the metering.

With its wide angle equivalent to
a 28mm lens, the F828 is able to encompass a large portion of
the building's wings. At this distance, the image shows no major
distortion and the exposure is very well-balanced.
ZOOM PHOTO
Zoomed to the maximum, and even with the Multi metering pattern,
the brightness of the image is easily affected by what is at the centre
of the frame, resulting in brighter or darker images. With this shot, the
auto exposure was based on the wall to the right, and the image reframed.
The result is an exposure that captures a lot of detail in the shadow areas,
and still avoids burning out the highlights.

With its 8 megapixel CCD, the DSC-F828
is able to capture more detail than cameras that have a longer
zoom, but a lower resolution. For example, in the image shown
below which is cropped from the original frame, the F828 effortlessly
captures the small aluminium sign on the glass door.
NIGHT PHOTO
As this camera is capable of long exposures, a series of photos
taken at night and at various ISO settings is included.
With this subject, an exposure
of 7 seconds at f7.1 is sufficient to capture a life-like image.
But the DSC-F828 is capable of a maximum exposure time of 30
seconds, a sufficiently long enough time to capture most types
of night time images, and do so at 64 ISO.
The F828 is equipped with a noise reduction system that captures a second
frame of the same duration as the first, using the intrinsic noise picked
up during the second exposure to eliminate it from the first.
In this case, the process means the
complete exposure lasted 14 seconds, plus another 10 seconds
or so to store the TIFF file.
This particular image,
one in a series, was captured in the early evening while the
temperature was hovering around -15°C (approx. -9°F).
Although the ocean is calm, the slight movement of the tugs over
the time of the exposure causes a slight blur.
It is worth noting however that noise is generally low, even in the darker
areas, the cold may have minimized it, and another exposure under warmer
conditions might have contained slightly more noise.
