It's intended to give an idea of how well various cameras render a range of skin tones, but it often winds up as more of a referendum on the camera's white balance system. The background of the image has a lot of blue in it, which frequently tricks white balance systems into overcompensating toward warmer hues.
The poster is also rather low resolution, having been made from a 20 megabyte digital file. As such, it can't be relied upon to reveal much about detail rendition of modern, high-megapixel cameras. Many are interested in close-up or "macro" photography. This test shows the best results we could obtain using each camera's macro mode. What to look for:. This subject is a good all-around laboratory test target, useful for the more analytically-minded in making objective comparisons between cameras.
Things to look for:. The results in the tests below mirror those seen above in other test shots. The test series are repeated here, for the benefit of our more quantitatively-oriented readers.
Low light photography is an area where there are really enormous differences between digital camera models. This test starts at a light level about equivalent to typical city street lighting at night one foot-candle , and then progresses down from there, each successive test being at half the light level of the preceding one.
You may also see the effect of poor low-light autofocus in some of these shots, although we use a different test setup to check autofocus performance more directly. The results of which are reported on in the main Test Results section.
Things to look for here include:. Digital camera makers have gotten better with their flash-range ratings. In the early days, many cameras had rather "optimistic" flash range specs, to put it politely. These days, the manufacturers seem to be toeing the line.
No doubt at least in part because of tests like this. Consistent with our philosophy of testing worst-case conditions, this test also involves some use of each camera's zoom lens. Flash range is greater at wide angle focal lengths than at telephoto ones. If you're shooting at the wide angle end of the lens' range, you might get better flash range than what's shown here. This is the standard ISO resolution target. It can be used with automated image-analysis tools like Imatest, but for our reviews, we generally just report the number of lines of resolution that we can see cleanly resolved in it.
The chart numbers correspond to hundreds of lines of resolution per picture height. Height to width ratio. In evaluating lines of resolution, it's important to set as a threshold the point at which artifacts jaggies or blurring of the lines start to overcome the target details themselves.
We tend to be a bit more conservative than some reviewers in the number of lines we'll say a camera has: The point here isn't to try to figure out the point at which you can just barely convince yourself that you're still seeing the target lines, but rather to call a halt when the camera is no longer cleanly resolving the target detail. We also report the point at which the target lines entirely merge into oblivion, as the "extinction point. Viewfinder accuracy is an important parameter, especially for shots where framing is critical.
It's likely that this is a deliberate design choice by the camera engineers, to help avoid users accidentally cutting off the heads of their subjects.
Unlike the optical viewfinders, the LCD viewfinders on most digital cameras tend to be quite accurate. Look for: Overall color : Matching summer sunlight here in the South, the lighting in this scene is a bit more yellow-tinged than that in many parts of the country, or in the fall or winter.
That said though, there's a fair range of color represented in the bouquet, presenting a tough challenge for the cameras. For some reason, the blue flowers seem particularly hard to handle, with many cameras rendering them as purple.
In real life, they're a light shade of navy blue, with just a bit of purple in them. Skin tones : The overall slight warm cast will tend to leave Marti's skin tones a bit on the warm side as well. Nonetheless, look to see if her skin seems overly pink or if they have a too-bright tinge of yellow: Some cameras oversaturate skin tones make their color too intense , leading to an almost sunburned look. A little oversaturation can make for a more "healthy-looking" complexion, but it doesn't take much variation for skin tones to look unnatural.
Highlight detail : When Marti's skin tones are at a more or less normal level of brightness, how much detail can you see in her shirt? Does it blow out entirely to white, or can you still see the creases and folds in the fabric? Overall contrast : Most consumer digital cameras produce bright, contrasty images, because that's what most consumers like.
Unfortunately, under bright sunlit conditions, many such cameras produce images with little or no highlight detail, and dark, plugged-up looking shadows. Shadow detail : The area under the flower bouquet is in quite deep shadow.
Does the camera in question retain good detail here, with low image noise? To see, you may need to download the image and play with it in Photoshop tm or another imaging program. Particularly for a camera that you can carry in most any pocket, the Sony DSC-W55 boasts a lot of features, and the controls are laid out well.
Offering good sharpness and color, a strong feature set, and available in four colors black, pink, silver, or blue , all at an attractive price, the Sony DSC-W55 has a lot going for it. If it only did a bit better job under incandescent lighting, it'd be a shoo-in for a Dave's Pick, but as it stands, it's a very near miss.

Works with on-camera flash to extend flash range. Reduces red-eye by allowing the flash to be separated from the camera. Fastens to the tripod mount, fires whenever the built-in flash does. Fully automatic. Colors are accurate but slightly oversaturated, especially the reds and oranges. Noise is the biggest issue with these models: while barely visible at ISO 80, smearing from the noise-reduction algorithm becomes evident at ISO and starts to develop severe color shifts at ISO and beyond.
It's better than nothing if you can't use the flash, however. The Sony Cyber Shot DSC-W50 is a decent ultracompact digital camera that makes up for its lack of controls with its solid performance and image quality. Its high sensitivity can give you passable low-light shots if you can get past the noise, and its compact form makes it an easily pocketable piece of tech.
The Good Compact; easy operation; decent image quality. Feels flimsy; noisy at high ISO; few scene modes or manual controls.
