We shot samples of this image with the automatic k , daylight k , and manual k white balance modes, this time choosing the daylight setting for our main series. It was actually a bit of a tossup between the white balance options: Auto was a bit cool, Daylight a bit warm, Manual a bit green.
We flipped a coin and picked Daylight. Resolution looks pretty good, with a fair amount of detail visible in the tree limbs, shrubbery, and bricks, though the overall image is quite soft. Still, we distinguished the subtle details of the bricks and in the leaves of the trees. A moderate amount of noise pervades the roof shingles, as well as the shadow areas across the house front.
About a pixel of a halo effect around the light and dark edges of the white trim along the roof line gives away the in-camera sharpening. The table below shows the full range of resolution and quality settings. The High setting does a nice job of increasing the image sharpness without altering the contrast too much, or creating too great a "halo effect" at contrast boundaries.
Contrast is altered slightly, but not enough to make any major difference in the image as a whole. While the low contrast option dims the image somewhat, and the high contrast one brightens it overall, neither is too severe an effect when compared to what we've seen with contrast options in some other cameras.
Overall, a useful feature. All three settings perform nicely, increasing or decreasing the tonal saturation just enough without changing the contrast or hue values. NOTE that this image cannot be directly compared to the other "house" shot, which is a poster, shot in the studio.
The rendering of detail in the poster will be very different than in this shot, and color values and even the presence or absence of leaves on the trees!
In general though, you can evaluate detail in the bricks, shingles and window detail, and in the tree branches against the sky. Compression artifacts are most likely to show in the trim along the edge of the roof, in the bricks, or in the relatively "flat" areas in the windows. We shot samples of this image with the automatic, cloudy, daylight, and manual white balance modes, choosing the automatic setting for our main series.
Both the cloudy and daylight settings produced warm, slightly magenta results, while the manual setting appeared a little greenish in places.
Overall color balance looks good in the automatic setting, though maybe just a hint warm. This shot is a strong test of detail, given the practically infinite range of fine detail viewable in a natural scene like this when seen from a distance. Resolution looks pretty good, judging by the pine needles and tree branches against the sky, as well as the brick details. Again, we noticed that the entire image is a bit soft.
We also judge a camera's dynamic range in this shot, comparing how well the camera holds detail in both the shadow and highlight areas. The QVUX Plus shows a somewhat limited range, losing all but the most prominent details in the bright bay window area. The dark shadow area over the doorway also shows a minimal amount of detail. Noise is minimal in the roof shingles and shadow areas, with a very fine grain pattern that we've noticed throughout our testing.
We also snapped images at the 80 k , k , and k ISO settings, noticing that the overall exposure darkened very slightly as the ISO setting increased. As usual, noise also became more pronounced with the higher ISO settings. The table below shows the full resolution and quality series. Likewise, the Low adjustment dimmed the image. Because of the heightened contrast in the High setting, the image also appears slightly sharper.
The High setting is also quite effective, brightening the entire image and making the colors very vibrant. We're puzzled by the greater effect this adjustment had on this shot than the House poster test target. Thus, we're happy to present you here with the following series of shots, showing the field of view with the lens at full wide angle, the lens at full 3x telephoto and the lens at full telephoto with 2x and 4x digital telephoto enabled.
The field of view at full wide angle is quite large, with barely any barrel distortion perceptible. The overall image noticeable sharpens with the 3x telephoto setting, and the prominent details return to the bright white paint of the bay window. The 2x digital telephoto gets closer in, and manages to maintain a reasonable amount of resolution and sharpness, with little noise. The 4x digital telephoto setting, however, becomes much softer with only a slight loss of resolution and rise in noise.
All of these images were shot at the camera's x resolution. At this image size, the 2x digital telephoto looks fine, since the x image size corresponds to the area it's cropping out of the center of the CCD sensor array. The 4x digital telephoto interpolates to enlarge a x block of sensor pixels to the x size, and the sharpness suffers accordingly. Both the automatic and daylight settings produced similar, warm images, with a somewhat orange cast overall. The manual setting by comparison was rather cool.
The large amount of blue in the image often tricks digicams into overcompensating, and the QV apparently somewhat fell prey to this challenge. As with the indoor portrait shots, a simple "auto levels" operation in Photoshop greatly improved the color rendition, as seen here. Resolution also looks nice, as the bird wings and silver threads on the blue robe show good detail. The color gradations on the wings are visible, but the details of the bird legs are a little pixelated. The violin strings appear reasonably sharp, but we detected a slight moire pattern.
Noise is moderate in the background and shadow areas, some of which could be from the actual poster.

Page Attaching An External Flash Unit Attaching an External Flash Unit Always make sure that the external flash unit is turned off before attaching it to detaching it from the camera. Leaving the flash unit on can cause it to fire unexpectedly.
Point the lens of the camera straight forward, so it matches the optical axis of the external flash. Page Turn on camera power and make the required camera settings. Page If this happens, try expanding the coverage angle decreasing the guide number of the flash unit.
Because of this, you may have to make adjustments of the ISO setting of your external flash unit to obtain the desired results. The type of cable you should use depends on what kind of computer you are connecting to. Page AC adaptor is recom- mended whenever performing data communication with the camera. In addition to sup- port for the DCF protocol, your CASIO digital camera also use dates in image folder names and image file names, which helps to make data management easier.
