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
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 reach of the Optio T10's built-in flash is limited when
the sensitivity is set to 80 ISO. Therefore, to obtain a brighter
image the sensitivity is set to Auto, which allows the camera
to boost it to 160 ISO. Nevertheless, some light fall-off
can be seen in the corners of the image.

Seen at full scale — at 100%
— on a monitor, the image shows practically no noise.
A slight yellow cast is detectable, probably due to the influence
of the incandescent lighting on the Auto white balance. And
sharpness is a bit soft as some of the smaller details in
the image have lost some definition.
ZOOM PHOTO
Now we zoom in on the 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 maximum aperture available to the T10 is f5.2,
smaller than at the wide angle end, and to boost the effect
of the flash the camera increases the sensitivity to 320 ISO.
The colour rendition of the image is comparable to the wide
angle shot; while noise is limited to the darker areas of
the image. Seen at 100%, a soft focus can seen throughout
the image.

MACRO PHOTO
Using the Optio T10's Macro mode, causes the camera
to automatically lock the zoom at the wide angle end. At this
focal length, the lens is able to focus on a subject 15cm
(6 inches) from the front element of the lens, producing an
image that has a field of view of approximately 14.5 cm (5.8
inches).
At this focal length, a fair bit of barrel distortion can
be seen in the image when there are image element with straight
lines aligned to the edges of the frame.
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 default multi-pattern metering of the T10 captures a
perfectly exposed image of the building, but overexposes the
pale blue sky slightly. Still, the image reveals an excellent
level of detail in the shadow areas such as the entrance.
And, as can be seen in the image below cropped from the full-size
frame, there is no chromatic aberration, and the barrel distortion
observed with the macro mode is not perceptible with this
subject.

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, the camera yields another very well exposed image,
balancing areas that are directly lit and those in the shade
so that both zones show detail. The result is an image that
clearly shows the inscription on the right side door, and
yet shows a great deal of detail in the much darker area behind
the glass doors.
As with the wide angle shot, no chromatic aberration is detectable,
nor is there any pincushion distortion.

NIGHT PHOTO
As this camera is capable of a long exposure, a photo
taken at night is included.
Aperture: f2.7; shutter
speed: 4 sec, 160 ISO.
The Night Scene mode
of the T10 is the only mode that allows an exposure time longer
than 1/4 second, extending the maximum exposure time to 4
seconds. Moreover, the Night Scene mode offers control over
the white balance — making it possible to set it to
tungsten to obtain more accurate colours — and control
over the ISO sensitivity.
With this flexibility, it is therefore possible to obtain
reasonable night photos.
With the subject shown here, a wide angle
(f2.7) 4-second exposure at 80 ISO — least sensitive to
noise — yields a relatively dark image. Increasing sensitivity
to 160 ISO increases the noise in the image only marginally,
and produces a much brighter image which softens the image sharpness
somewhat. It is still possible, however, to see a reasonable
level of detail, and colours are quite faithful.
