Sony DSC-H3 Exposure
Sony Cyber-shot DSC-H3 Exposure
Saturation & Hue Accuracy
Good overall color, though strong oversaturation in the reds. About average performance in terms of hue accuracy.
Saturation. The Sony Cyber-shot DSC-H3 oversaturates strong red tones quite a bit, but actually undersaturates some of the greens. Still, overall color and saturation were pretty good, though the bright reds do tend to dominate depending on the scene. Most consumer digital cameras produce color that's more highly saturated (more intense) than found in the original subjects. This is simply because most people like their color a bit brighter than life.
Skin tones. The Sony H3 did produce somewhat warm skin tones, though results were still quite good and natural. Most people prefer slightly warm skin tones over cooler, more bluish ones. Where oversaturation is most problematic is on Caucasian skin tones, as it's very easy for these "memory colors" to be seen as too bright, too pink, too yellow, etc.
Hue. Overall hue accuracy was about average, as the Sony H3 pushed cyan toward blue and some reds toward orange. Hue is "what color"
the color is.

Exposure and White Balance
Indoors, incandescent lighting
Warm color balance with both Auto and Incandescent settings. More than average positive exposure compensation required.
|Auto White Balance
|Incandescent White Balance
Color balance indoors under incandescent lighting was very warm with both the Auto and Incandescent white balance settings, though the Auto option had the slightly lesser cast. The strong warm cast results in slightly orange skin tones. The Sony H3 required a +1.3 EV exposure compensation boost to get a good exposure, which is more than average for this shot. In addition to the warm, orange color balance, the blue flowers are quite dark and purplish. (Many digital cameras reproduce these flowers with a dark, purplish tint, so the DSC-H3 struggled a bit here.) Our test lighting for this shot is a mixture of 60 and 100 watt household incandescent bulbs, a pretty yellow light source, but a very common one in typical home settings here in the U.S.
Slightly flat color, though pretty good exposure. High default contrast, but better results with the low contrast setting.

Outdoors, the Sony Cyber-shot DSC-H3 produced high contrast exposures in response to the harsh lighting. Exposure was pretty good though, as the camera actually required a little less than the average amount of positive exposure compensation on the portrait shot. The default contrast setting resulted in very dark shadows and strong highlights, but the low adjustment produced a more even exposure. The Sony H3 features a Dynamic Range Optimizer setting, but results were not much better than the standard contrast setting. Overall color looks just a hint flat on the house shot, thanks in part to slight undersaturation in the green tones.
High resolution, 1,500 ~ 1,600 lines of strong detail.
|Strong detail to

Our laboratory resolution chart revealed sharp, distinct line patterns down to about 1,600 lines per picture height horizontally, and to about 1,500 lines vertically. Extinction occurred right at 2,000 lines. Use these numbers to compare with other cameras of similar resolution, or use them to see just what higher resolution can mean in terms of potential detail.
Sharpness & Detail
Fairly sharp images overall, though noticeable edge enhancement. Noise suppression limits detail in the shadows.

Sharpness. The Sony Cyber-shot DSC-H3 captures fairly sharp images overall, with pretty good detail definition. However, in the crop above left, edge enhancement is visible along the lines of high-contrast areas such as the house trim. Edge enhancement creates the illusion of sharpness by enhancing colors and tones right at the edge of a rapid transition in color or tone.
Detail. The crop above right shows fairly high noise suppression, with darker areas of Marti's hair showing limited detail. Individual strands become lost, but are hinted at with color transitions in the lighter shadows. Noise-suppression systems in digital cameras tend to flatten-out detail in areas of subtle contrast. The effects can often be seen in shots of human hair, where the individual strands are lost and an almost "watercolor" look appears.
ISO & Noise Performance
Low to moderate noise at the normal sensitivity settings, though a big jump in noise with strong blurring at the higher settings.
|ISO 100||ISO 200||ISO 400|
|ISO 800||ISO 1,600||ISO 3,200|
The Sony Cyber-shot DSC-H3 produced low to moderate noise at the ISO 100 and 200 settings, though noise is slightly high at ISO 400. At ISO 800, there's a significant jump in the noise level, with stronger blurring. At ISOs 1,600 and 3,200, the higher noise drastically interferes with the image, altering color and practically eliminating all fine detail.
Extremes: Sunlit and low light tests
High resolution with strong overall detail, though high contrast with default setting. Good results with the contrast adjustment. Excellent low-light performance, capable of capturing bright images in near darkness.
|0 EV||+0.3 EV||+0.7 EV|
|+1.0 EV||+0.7 EV, Low Contrast||Dynamic Range Optimizer|
Sunlight. The Sony Cyber-shot DSC-H3 had some difficulty dealing with the deliberately harsh lighting in the test above, producing very high contrast with washed-out highlights and deep shadows at its default contrast setting. Shadow detail is limited, with the effects of noise suppression evident in the form of smudged detail in deep shadow areas. The camera required about average compensation to get proper exposure of skin tones, at +0.7 EV. The camera's low contrast adjustment did a good job of producing a more even exposure, with better shadow detail. The Sony H3 also offers a Dynamic Range Optimizer setting, but results here were only slightly better than the normal contrast setting. Of the three, the shot taken with the low contrast option produced the best overall results. Of course, consider using the fill flash for better results in harsh lighting like this, or move to bright shade.
Because digital cameras are more like slide film than negative film (in that they tend to have a more limited tonal range), we test them in the harshest situations to see how they handle scenes with bright highlights and dark shadows, as well as what kind of sensitivity they have in low light. The shot above is designed to mimic the very harsh, contrasty effect of direct noonday sunlight, a very tough challenge for most digital cameras. (You can read details of this test here.)
Low light. The Sony Cyber-shot DSC-H3 performed well on the low-light test, capturing bright images at the lowest light level with the lowest sensitivity setting (ISO 100). Noise increased with higher ISOs, as you might expect, but results are good at ISO 100 (if just a hint dim at the 1/16 foot-candle setting). Color balance was pretty good with the Auto white balance. The camera's autofocus system worked fairly well, though it was not a match for its exposure system. It was able to focus on the subject almost down to the 1/8 foot-candle light level unassisted, but down to the darkest light level with the AF assist enabled. (A useful trick for shooting in low light is to just prop the camera on a convenient surface, and use its self-timer to release the shutter. This avoids any jiggling from your finger pressing the shutter button, and can work quite well when you don't have a tripod handy.)
How bright is this? The one foot-candle light level that this test begins at roughly corresponds to the brightness of typical city street-lighting at night. Cameras performing well at that level should be able to snap good-looking photos of street-lit scenes.
NOTE: This low light test is conducted with a stationary subject, and the camera is mounted on a sturdy tripod. Most digital cameras will fail miserably when faced with a moving subject in dim lighting. (For example, a child's ballet recital or a holiday pageant in a gymnasium.) For such applications, you may have better luck with a digital SLR camera, but even there, you'll likely need to set the focus manually.

Coverage and Range
A modest flash at close range, and definitely not a match for the camera's 10x optical zoom. Our standard shots required much higher than average exposure compensation, though coverage was pretty uniform.
|38mm equivalent||380mm equivalent|
Flash coverage was slightly uneven at wide angle, but still a little better than average. At full telephoto, the target was too far away for the flash to illuminate it. In the Indoor test, the Sony H3's flash underexposed our subject quite a bit at its default setting, requiring a +1.7 EV exposure compensation adjustment to get good results. And even here, the exposure is still a bit dim. The camera's Slow-Sync flash mode produced slightly brighter and more even results, though with a stronger orange cast from the room lighting. Again, the camera required a +1.7 EV exposure boost, though results are brighter from the longer shutter time.
ISO 100 Range. At wide angle, flash shots at ISO 100 remained fairly bright out to a distance of about 10 feet, decreasing in brightness slightly from that point on. At full telephoto and ISO 100, the target remained bright to about 8-9 feet, but the images darken gradually from there.
|Manufacturer-Specified Flash Range|
Manufacturer Specified Flash Test. In the wide angle shot above, the DSC-H3 seems to perform exactly as Sony says it will, producing a good exposure at the rated distance with its ISO set to Auto (which selected ISO 100). Our standard test method for flash range uses a fixed setting of ISO 100, to provide a fair basis of comparison between cameras. We've now also begun shooting two shots using the manufacturer-specified camera settings (or one if the company only specs one), at the range the company claims for the camera, to assess the validity of the specific claims.
Good print quality, good color, good 13x19-inch prints. ISO 400 images are soft but usable at 11x14, ISO 800 shots are still good at 8x10.
When printing our indoor incandescent light shots, the story changes, but only a little. ISO 100 shots look better at 11x14, ISO 400 shots still look good at 11x14, ISO 800 shots still look good at 8x10, and ISO 1,600 is still usable at 5x7. ISO 3,200, on the other hand, is too muddled by false colors to pass muster even on a 4x6 print. This is a pretty expected and common outcome, as the incandescent light challenges the sensor's blue channel too much. Again, though, quite good overall.
Testing hundreds of digital cameras, we've found that you can only tell just so much about a camera's image quality by viewing its images on-screen. Ultimately, there's no substitute for printing a lot of images and examining them closely. For this reason, we now routinely print sample images from the cameras we test on our Canon i9900 studio printer, and on the Canon iP5200 here in the office. (See the Canon i9900 review for details on that model.)
