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 built-in flash of the Cx7430 is set to Auto, and fires to provide fill
light to the subject. The flash provides good edge to edge coverage for
the subject, and there is no noticeable light falloff in the corners of
the frame.

While the colours captured by the
Automatic white balance are correct, there seems to be a slight
loss of sharpness — visible in the penciled price at the
top of the photo paper — likely because of the compression.
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.
Zoomed in, the Auto white balance remains flawless, producing
an image that exhibits colours that are faithful to those captured
at the wide angle
setting although the frame contains a different distribution of colours.

Still, here too, the slight softness
caused by the compression can be seen in the image.
MACRO PHOTO
The CX7430 has a macro mode that lets the camera focus on
a subject between 13 to 70 cm (5.1 to 27.6 inches) from the lens
at the wide angle setting and 22 to 70 cm (8.7 to 27.2 inches)
when the zoom is at the maximum telephoto position.
At the wide angle end and at the closest approach, the camera captures
a field of view which measures 10 cm (3.9 inches) horizontally, and 8 cm
at the telephoto end.
Aperture: f4.6, shutter speed: 1/91sec., 80 ISO.
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.
The multi-zone metering system of the Kodak CX7430 reliably produces images
that are well exposed. But, as noted in the Image Quality section of this
review, photos which are captured in bright sunshine have colours that
are quite saturated, as can be seen here.

ZOOM PHOTO
At the maximum telephoto setting of the lens, the Kodak avoids overexposing
the foreground at the expense of the deeply shadowed entrance which is
then slightly underexposed.
The photo also shows that the lens has no noticeable pincushion distortion,
as evidenced by the very straight vertical image elements that are aligned
on the edges of the frame.

NIGHT PHOTO
Since this camera is capable of long exposures,
a photo taken at night is included here.
Aperture: f2.7; shutter
speed: 4 sec., 80 ISO.
The Kodak CX7430 has a Long Time
shutter option, activated in the menu, that allows up to a 4
second exposure. A four-second exposure is sufficient to photograph
city lights at night.
Set to the LT mode, the camera takes control of ISO (CCD sensitivity)
and white balance. The ISO speed is automatically set to 80 ISO to avoid
noise, and the white balance is correctly evaluated.
A noise reduction system is used,
doubling the time necessary to capture an image by capturing
a dark frame — an image captured without opening the shutter — from
which noise can be determined and then eliminated from the first
exposure prior to saving the image.
The system is quite efficient, and as can be seen in the image below which
has been cropped from the original frame, the results are quite good.
