I've begun including links in our reviews to a Thumbnail index page for the test shots. The data on this page includes a host of information on the images, including shutter speed, ISO setting, compression setting, etc. Rather than clutter the page below with all that detail, we're posting the thumbnail index so only those interested in the information need wade through it!
"Sunlit" Portrait: (This is my new "Outdoor" Portrait test - read more about it here.)
High resolution and good detail, with pretty good color. Contrast is high, with reduced detail in the highlights and shadows.
Exposure compensation: +0.7 EV, about average.
Contrast/Tone: High contrast, very bright highlights and dark shadows, both with somewhat limited detail.
White Balance: Auto and Daylight settings both slightly cool, Manual slightly warm, I chose the Daylight as most pleasing.
Color accuracy: Really excellent, all colors look very good.
Skin tones: Slightly pink, but very close to just right.
Resolution/sharpness: Good for its class, slightly soft details but still good definition.
Shadow detail: Slightly limited, moderate noise.
To view the entire exposure series from zero to +1.0 EV, see files CP46OUTMP0.HTM through CP46OUTMP3.HTM on the thumbnail index page.
Increased resolution and stronger detail, but contrast is again high.
Exposure compensation: None required, a bit less than average. (The shot looks a little dark due to the deep shadows, but boosting the exposure compensation to +0.3 EV lost too much in the highlights, in my opinion.)
Exposure/Tone: High contrast creates dark shadows and harsh skin tones.
Detail: Stronger than the wider shot, but still slightly soft.
Distortion: Good, 3x zoom lens avoids distortion close-in like this.
To view the entire exposure series from zero to +1.0 EV, see files CP46OUTFACAP0.HTM through CP46OUTFACAP3.HTM on the thumbnail index page.
Slight underexposure with the flash in the normal setting, but a brighter exposure with the Slow-Sync mode (though a strong orange cast).
Exposure: Results pretty good at +0.7 EV. (Default exposure quite dim.) Slow-Sync mode is brighter at +0.7 EV, but with stronger color cast. Party mode is a little dim, but coverage is more even.
Flash balance with room lighting?: Good in normal mode, but slow-Sync mode results in orange and blue tints. (Blue from the flash, orange from the room lighting.)
Color: Somewhat reddish skin tones, but good color in the bouquet.
To view the entire exposure series from zero to +1.3 EV in the normal flash mode, see files CP46INFP0.HTM through CP46INFP4.HTM on the thumbnail index page.
To view the exposure series from zero to +1.0 EV in the Slow-Sync flash mode, see files CP46INFSP0.HTM through CP46INFSP3.HTM on the thumbnail index page.
High resolution and strong detail, but high contrast limits the dynamic range.
This image is shot at infinity to test far-field lens performance, and to present a near-infinite range of detail to the camera. NOTE that this image cannot be directly compared to the other "house" shot, which is a poster, shot in the studio.
Sharpness/Detail: High resolution and good detail, about average for a 4.0-megapixel camera.
Sharpness in Corners: Good, very slight falloff.
Color: Good, slightly dark-looking though.
Dynamic Range: Surprisingly good, some detail held in highlights, shadow detail is a little weak though.
Detail lost to anti-noise processing?: None noticeable.
The Coolpix 4600's focal length range of 34-102mm equivalents is typical of most point & shoot digital cameras. It corresponds to a moderate wide angle to a modest telephoto.
Cool, slightly magenta color with Manual or Daylight settings, but still good overall. Strong detail.
White Balance: Manual and Daylight settings very similar, though Daylight a hint warmer. (Manual setting produced cooler skin tones.) Auto setting too warm.
Color: Pink skin tones. Blue robe and background both purplish.
Sharpness/Detail: Strong detail with good sharpness and definition. (Close to the limits of the poster though.)
Good color, though slightly warm, and pretty good exposure as well.
White balance: Manual setting best overall, though slightly warm, Daylight very similar. Auto setting reddish.
Color Accuracy: Good hue accuracy, but bright additive primary colors (reds, greens, blues) are greatly oversaturated. "Real world" pictures should be pleasing to most consumers though, partly because the camera oversaturates pastels and skin tones only slightly.
Shadow detail and noise: Limited detail in the briquettes, moderate noise.
Limited low-light shooting capability, images only bright to 1/2 foot-candle. (Should be sensitive enough for average city night scenes, but nothing darker). Very limited low-light autofocus performance, barely able to focus under typical city street lighting.
Exposure limit: 1/2 foot-candle. (About 1/2 as bright as typical city street lighting at night.)
Autofocus Limit: Slightly brighter than 1 foot-candle, marginal for city night scenes.
White Balance: A little warm-toned.
Noise Levels: Moderately high, even at the brighter light levels.
Detail loss to anti-noise processing?: Minimal at one foot-candle, but more at the lower light levels (though images are really too dark to judge).
General Notes: No manual ISO adjustment or exposure settings. Maximum shutter speed of two seconds limits low-light shooting. Autofocus system is only barely good enough for bright city street lighting at night. - Don't look to this camera if you're interested in after-dark available-light photography.
(Note: If you'd like to use a light meter to check light levels for subjects you might be interested in shooting, a light level of one foot-candle corresponds to a normal exposure of two seconds at f/2.8 and ISO 100.)

Flash Range Test
Bright flash to about nine feet (reasonably bright at 10), though decreasing intensity from there. Also, camera "cheats" somewhat, by boosting its ISO, making for noisy flash photos much beyond 8 feet.
Flash range at telephoto lens setting: Nine ~ 10 feet.
Good resolution, 1,100 - 1,150 lines of "strong detail." Very high barrel distortion at wide angle, though almost no distortion at telephoto. Moderate to high chromatic aberration, slightly soft corners (but better than average).
