Panasonic DMC-FX500 Exposure
Panasonic Lumix DMC-FX500 Exposure
Saturation & Hue Accuracy
Very good overall color and hue accuracy, with only minor oversaturation of some colors.
Saturation. The Panasonic DMC-FX500 produced accurate saturation overall, though strong reds and blues are just a hint oversaturated. Results are very good here. 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. With proper white balance, the DMC-FX500's skin tones were a little on the pink side, but still pleasing. 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. The Panasonic Lumix DMC-FX500 showed only a few small color
shifts relative to the correct mathematical translation of colors in its
subjects. Cyan was pushed a tad toward blue and some yellows toward green,
though overall hue accuracy was good and believable. Hue is "what
color" the color is.

Exposure and White Balance
Indoors, incandescent lighting
Pretty good color with Manual white balance, though a hint magenta. More than average positive exposure compensation required.
|Auto White Balance
|Incandescent White Balance
|Manual White Balance
Color balance indoors under incandescent lighting was quite magenta in Auto white balance mode, but very warm in Incandescent mode. The Manual option produced the most accurate results overall, though with a very slight magenta cast. Overall color looks pretty good, though skin tones here are a bit on the pink side, and the white elements in the composition have a very slight magenta tint as well. The DMC-FX500 required a +0.7 EV exposure compensation boost to get a good exposure, which is a little higher than the average exposure 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.
High contrast, but still good overall color and exposure under harsh conditions.

Outdoors, the Panasonic Lumix DMC-FX500 produced generally good color and exposure, though contrast is high. Detail is strong in the shadow areas, though noise pixels interfere with definition in the finer details here. In the portrait above, the slightly high EV boost pushed the highlights in the white shirt, though some detail is preserved. The camera's Intelligent Exposure mode did attempt to balance the exposure, but with the amount of positive exposure compensation needed here, the highlights remain quite bright.
Very high resolution, 1,700 lines of strong detail.
|Strong detail to
1,700 lines horizontal

Our laboratory resolution chart revealed sharp, distinct line patterns down to about 1,700 lines per picture height in both directions. Extinction didn't occur, and lines at 1,800 are still fairly distinct. 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, with only minor edge-enhancement on high-contrast subjects. Some noise suppression limits detail in the shadows, and image noise grain decreases detail definition in some areas.

Sharpness. The Panasonic Lumix DMC-FX500 captures a lot of fine detail, though detail definition suffers from both noise suppression and noise grain. Slight enhancement artifacts are visible on high-contrast subjects such as the crop above left. 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 moderately high noise suppression, with the darker areas of hair showing limited detail, as individual strands are only hinted at. Though the camera does attempt to reduce the effects of noise here, some noise grain also reduces fine detail. 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
Moderate noise at the normal sensitivity settings, though stronger noise and noise suppression at the higher settings, resulting in blurred detail. Adjustable Noise Reduction setting trades detail for fewer noise pixels.

The Panasonic Lumix DMC-FX500 produced moderate to moderately high noise at the lower sensitivity settings, with the noise grain interfering slightly with detail definition. At ISO 400, noise and noise suppression become more evident, in the form of smudged detail. At ISOs 800 and 1,600, noise grain is much more prevalent, altering color balance and decreasing fine detail. The camera's maximum ISO 3,200 setting is only available at the 2,048 x 1,536-pixel resolution, and efforts by the camera to hold down the noise levels result in a very blurry image altogether. The DMC-FX500 does offer an adjustable Noise Reduction setting for all ISOs except 3,200, which reduces noise in five settings. The last set of crops show the 400, 800, and 1,600 ISO equivalents at the maximum noise reduction level, and you can see that the camera trades detail for decreased noise pixels. So, there is a trade-off for decreased noise in the form of blurred details.
Extremes: Sunlit and low light tests
High resolution with strong overall detail, but high contrast. Slightly limited low-light capabilities, but able to capture bright exposures in near darkness.
|+0.7 EV||+1.0 EV||+1.3 EV|
Sunlight. The Panasonic Lumix DMC-FX500 produced high contrast under the deliberately harsh lighting in the test above, with washed-out highlights and deep shadows. Still, shadow detail is pretty good, though noise pixels and noise suppression do interfere here. At +1.0 EV, the highlights on the white shirt are almost too hot, but the overall exposure looks better here. The DMC-FX500 does feature an Intelligent Exposure mode, which attempts to correct for situations like this, and it did indeed produce a slightly more balanced exposure, though overall exposure was much too bright. Still, be sure to use fill flash in situations like the one shown above; and it's better to shoot in the shade when possible.
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 Panasonic Lumix DMC-FX500 was able to capture bright images down to the lowest light level at ISOs 400 and up. At the lower ISOs, the target is visible at the darker light levels, but quite dim. Some of the FX500's night scene modes would have helped here. Color balance looked pretty good, if a bit cool or magenta depending on the exposure, with the Auto white balance. The camera's AF system was able to focus unassisted down to just above the 1/16 foot-candle light level, and to total darkness with the AF assist. Overall, a pretty good performance despite minor limitations at the lower sensitivity settings.
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 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 slightly weak flash at close range, with uneven coverage. Exposure compensation had no effect on normal flash mode, resulting in a dim shot, though Slow-Sync mode produced brighter results.
|25mm equivalent||125mm equivalent|
|Normal Flash, Default Exposure||Slow-Sync Flash, +0.7 EV|
Flash coverage was quite uneven at wide angle, and still a bit uneven at full telephoto. In the Indoor test, the DMC-FX500's flash underexposed our subject at its default setting, though boosting the exposure compensation produced no effect on the overall brightness. The camera's Slow-Sync flash mode produced brighter and more even results, with a stronger pinkish-orange cast from the room lighting, and in this mode the exposure compensation did help brighten the exposure.
ISO 100 Range. At wide angle and ISO 100, flash shots were bright at six feet, though intensity decreased with additional distance. At full telephoto, exposures were already dim at six feet, and decreased in brightness from there.
|Manufacturer-Specified Flash Range|
Auto ISO 320
Auto ISO 400
Manufacturer Specified Flash Test. In the shots above, the DMC-FX500 performs about as Panasonic says it will, producing a good exposure at the rated distance with its ISO set to Auto (which selected ISO 320 and 400 to compensate). 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, at the range the company claims for the camera, to assess the validity of the specific claims.
Soft print quality, good color, soft 11x14-inch prints. ISO 400 images are soft but usable at 8x10, ISO 800 shots are better at 5x7.
Overall, ISO 100 is the best choice for detail, but it's surprising that there's not better luminance noise control. It's unfortunately a common problem with Panasonic point and shoots, but we haven't seen this kind of luminance noise on this scale before.
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 Pro9000 studio printer, and on the Canon iP5200 here in the office. (See the Canon PIXMA Pro9000 review for details on that model.)
