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 artefacts 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
With
this shot, the camera is set to Program mode, and the flash is set to
Auto. The subject is lit from above by a low wattage incandescent bulb,
and the camera's meter must evaluate the relatively bright items on the
table as well as the dark background.
The C-750UZ benefits
from a slightly more powerful flash than most other compact cameras, and
it is able to project light to the more distant elements in the scene.
In this photo, the metering accurately balances the incandescent light
with the flash, and records a detailed image.

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. In this case, the camera is pulled
back a bit farther than it was for the wide angle shot.
At the fullest magnification of the zoom, the C-750UZ needs to be at least
1.5 m (5 ft) from the subject to be able to focus. With this subject,
the camera had to be backed up about 30 cm (1 ft), which made it possible
to focus on one of the more distant items. As can be seen in the image
below, cropped from the full size image, the C-750UZ captures a high level
of detail.
Although
the C-750UZ has 2 macro modes, only one of these, Super Macro, lets the
camera focus on a subject a mere 3cm from the front element of the lens.
When the Super Macro mode is used, the depth of field can be very shallow
if the camera is left on Program mode. Using aperture priority and an
f8 aperture, the depth of field can be increased.
The
Super Macro mode locks the zoom at the best focal length, and provides
a field of view of 3.6 cm (1.4 in.) horizontally.
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 also often provides real-life information on the quality of the
exposure and reveals any noise that might be present.
Because
ED (Extra low Dispersion) glass is used for the lens of
the C-750UZ (and the C-740UZ), photos show very little of the chromatic
aberration that was easily noted with earlier UZ cameras. The images are
sharp, and very detailed.

At the maximum magnification
of the zoom, the metering is clearly influenced by the shadow areas which
become dominant in the frame. The result is that parts of the foreground
are notably overexposed.
However, the interior of the building is remarkably well imaged, and the
C-750UZ records distant details quite clearly. It is also worth noting
that the photo contains very little noise.

NIGHT
PHOTO
This
camera is capable of long exposures, and these images captured late at
night and over its ISO range give an idea of its capabilities.
Aperture:
2.8; shutter speed: 16 sec, 50 ISO.
With
a maximum exposure time of 16 seconds in the Manual mode, the C-750UZ
is capable of capturing photos under very low light.
A noise reduction mode, selected in the camera's menu, needs to be used
to reduce the effect of noise on the photos. The noise reduction system
is quite effective, but some bright pixels remain visible in long exposures,
particularly in those captured at the highest ISO setting.
The
images shown here were captured on a moon-lit night (behind the trees!).
The moonlight increased the ambient brightness.
At 50 ISO, the image remains fairly dark with this kind of subject, but
has the least noise. 50 ISO would be ideal for subjects that have some
light, such as a city skyline at night.
