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 wide angle of the E900's zoom captures a field of view
that is the 35 mm equivalent of 32 mm lens. The image it produces
is well-lit by the flash, and shows no light falloff in the
corners.
This image is captured using the JPEG format and the overall
sharpness of the image is slightly less than what can be obtained
using the RAW format.

Worth noting however, the pop-up
flash of the E900 has a limited range and lighting an average
size room often demands that the ISO be increased if the camera
is used with the Program or Priority modes, or set to Auto ISO
when the Auto shooting mode or the scene modes are used. Regrettably,
pushing the power of the flash often entails a gain in noise.
ZOOM PHOTO
Now we zoom in on a specific area. The intent
is to test the sharpness of the image at the zoom's maximum
setting. The camera remains at the same distance as with the
preceding photo.
This zoom photo on the other hand is captured using the
RAW format, which yields a greater level of detail. This can
be seen in the image shown below which is taken at 100% scale
from the 9 megapixel original.
The slightly grainy appearance of the image, caused by noise,
can also be noticed, although it is captured at the lowest
sensitivity setting of 80 ISO.
Macro shots that contain straight
image elements aligned by the long edges of the frame show some
barrel distortion, but the image sharpness is quite uniform
across the entire field of view.
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 building is photographed at noon on a partly sunny winter
day. Nevertheless, the light is quite harsh, and helps reveal
a chromatic aberration: a turquoise line below the beams.
The chromatic aberration is most pronounced at the brightest
aperture (f2.8) which is what the Program mode prefers. However,
closing down the diaphragm of the camera to around f6 tends
to eliminate the aberration, even at the widest angle.
A bit of colour noise can be seen as well, appearing as grain
in areas with the same colour.

This wide angle shot, and the zoom
shot of the building shown further down, are both captured using
the RAW format, and then converted to TIFF.
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.
The RAW format avoids the lossy compression of JPEG, and
therefore yields the best image quality that the camera
can produce.
As observed before, the E900 produces an image that shows
some noise, even at 80 ISO. Still, the exposure is quite good,
and details are captured in both the shadows and the areas
that are directly lit. Moreover, the chromatic aberration
that can be seen in the wide angle shot is absent with the
telephoto shot.

NIGHT PHOTO
Since this camera is capable of long exposures,
a photo taken at night is included here.
The Manual mode of the E900
has a shutter speed range of 1/2000 second down to 15 seconds,
and with a 15 second maximum exposure, it is well suited to
capturing night photographs.
The image presented here was saved in RAW format, and then
re-saved to TIFF using Photoshop CS II RAW Plug-in. The RAW
Plug in makes it possible to tweak for a wide range of parameters,
and this one was optimized through minor adjustments in sharpness,
colour balance, and colour noise before being saved.
Aperture: f6.4; shutter
speed: 15 sec., 80 ISO.
Interestingly, the E900 does
not appear to use the common dark-frame noise reduction system.
The camera captures the image — either in JPEG or RAW
— and saves it immediately.
Worth noting, while a turquoise fringe is easily detectable
when the maximum aperture is used, it is eliminated if the
diaphragm is closed down, as is the case here.
