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.
Using the default settings of the Z885 and with the CCD
sensitivity set to 80 ISO to prevent any noise, the camera
yields an image that is a touch too dark, and some light falloff
can be seen in the corners of the frame. Setting the sensitivity
to Auto ISO, the camera automatically goes up to 200 ISO and
yields a good exposure that shows even lighting.

At 200 ISO noise is minimal, even
in shadow areas. The overall sharpness is good and the colours
are quite natural.
ZOOM PHOTO
Now we zoom in on the centre of the image above to gauge the sharpness
of the image at the zoom's maximum setting. The camera remains at the same
distance as in the preceding photo.
With the zoom set to the maximum telephoto, and the sensitivity
set to auto, the camera again uses a setting of 200 ISO to
capture the image. The exposure is slightly darker than the
wide angle shot, but colours remain natural. Noise is nearly
undetectable and the image shows excellent sharpness, as can
be seen in the texture of the underlying drop cloth, and the
old photographic paper envelope.

CLOSE-UP PHOTO
The Z885 is capable of shooting close-ups, but not the type
of macro shot that has become expected of a digital camera.
At its closest approach to a subject, the Z885 has a focus
range of 20 to 70 cm (7.9 to 27.3 in.) when the zoom is at
the wide end, and 50 cm to 1 m (1.6 to 3.3 ft) when set to
the telephoto end; yielding, respectively, fields of view
of 25.3 cm (9.8 in.) and 9.6 cm (3.74 in.).
Using the Manual mode makes it possible
to obtain better results than other modes as it allows selecting
a small aperture — f14 in this case — which increases
the depth of field. Regrettably, with this type of photography
the low resolution of the monitor becomes a hindrance as it
is very difficult to ascertain the sharpness of smaller image
elements.
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.
Benefiting from the perfect lighting conditions of a summer
day, the Z885 easily produces a perfect exposure. Saturation
is excellent, particularly with blues and greens, allowing
the image to create a superb print.
There is no discernible barrel distortion, nor is there
any chromatic aberration, and sharpness is uniform across
the frame.

ZOOM PHOTO
Zooming in on the entrance of the building,
the shadowed entrance takes on a greater importance for the
metering and can cause an overexposure of sections that are
directly lit.
Zoomed in, the major characteristics of the image remain
identical to the wide angle shot. The exposure is excellent,
revealing a lot of detail in the areas of the frame that are
directly lit by the sun and those that are in shadow, such
as the elements behind the tinted glass doors. Here again,
we note the absence of any distortion or of chromatic aberration.

NIGHT PHOTO
Since this camera is capable of long exposures, a photo taken at night
is included here.
Aperture: f3.4; shutter
speed: 8 sec, 80 ISO.
Equipped with a full Manual
mode, the Kodak EasyShare Z885 allows the user to select the
sensitivity, the white balance, as well as the aperture and
shutter speed, making it possible to capture very good night
time images under relatively low-light.
The maximum exposure time of 8 seconds combined with a sensitivity
setting of 80 ISO allows the camera to produce an image that
contains details invisible to the unaided eye.
With the white balance set to
Tungsten (incandescent), the resulting image has colours that
are close to those that can be perceived.
The Z885 uses a noise reduction process that operates immediately
post-capture, using a dark frame to identify sources of noise
and delete them from the photo prior to saving it. The process
has some impact on the overall sharpness of the image when
it is seen at 100% scale on a monitor, but the residual noise
is undetectable when the image is printed, even with 8 x 10
(20 x 25 cm) prints.
