The above image was taken with the Sony Cyber-shot DSC-W310 in Program mode. The lens was set to 5 mm (28mm equivalent) and the metering selected an exposure of 1/1250th of a second at f4.3 with an ISO setting of 100. The original 4000 x 3000 pixel image had a file size of 4.38MB. Overall the Sony Cyber-shot DSC-W310 has done a very good job of capturing this scene. The image is perfectly exposed with detail in the shadows and highlights and the colours are quite pleasant. On the whole, the W310’s white balance had a slight tendency towards blue, but it was well within acceptable limits. Closer examination of the 100 percent crops taken from selected areas of the test image though show the W310’s image quality is not all that you’d expect from a camera in this price range. Wherever you look image detail just isn’t very crisply rendered. In the first crop the chapel on the hill and the rocks and grass in front of it look soft as do the foreground houses in the lighthouse crop. In all the crops there a granularity, or clumpiness that is visible in flat areas of colour like the sky and obscures fine detail elsewhere – on the balconies in the fourth crop for example. Because of its uniformity we’d say the most likely cause is heavy-handed processing. Certainly the image detail at the edges of the frame is no worse than at the centre. While the Nikon COOLPIX S3000 and Canon IXUS 105 / SD1300 IS are quite closely matched in terms of image quality (we reckon the COOLPIX S3000 just has the edge), in our view the Sony Cyber-shot DSC-W310 falls short of both of them. All of the Cyber-shot DSC-W310 crops are less clear and show less of the fine image detail than those from either of the other two compacts. This is most obvious if you compare the foreground in the first two crops. Now let’s check out how they compare at higher sensitivities in our High ISO Noise results. |
Sony Cyber-shot DSC-W310 vs Nikon COOLPIX S3000 vs Canon IXUS 105 / SD1300 IS High ISO Noise
|
 | To compare noise levels under real-life conditions we shot this scene with the Sony Cyber-shot DSC-W310, Nikon COOLPIX S3000, and Canon IXUS 105 / SD1300 IS. The lenses on all three cameras were set to approximate the same field of view and ISO was manually set. |
The above shot was taken with the the Sony Cyber-shot DSC-W310 in Program mode with the lens at a wide angle setting of 5mm (28mm). The exposure was 1/3 of a second at f3. The crops are taken from the area marked with the red square and presented below at 100%.
The most obvious problem with these crops from the Sony Cybershot W310 is the white balance. The W310’s white balance was set to auto and the interior of the church lit by daylight, but the W310 has opted for a white balance setting which would be more appropriate for artificial lighting and the result is a strong blue colour cast. The W310’s auto white balance had a tendency to err marginally on the blue side, particularly on indoor shots without flash, but nowhere did it get it as badly wrong as this. Under the circumstances we’d recommend you set the W310’s white balance to daylight or cloudy when shooting indoors using natural lighting.
So what about the high ISO noise performance of the W310? Even ignoring the white balance issue it’s not great news. At 100 ISO the Cyber-shot W310 does a passably good job with little visible noise and good detail in the shadows. But at 200 ISO there’s already evidence of deterioration. Take a look at the right edge of the stone column and the wood panelling in the bottom of the frame and compare it with the 100 ISO crop. As you’d expect, this gets progressively worse as you go up the sensitivity scale to 400 ISO and beyond. The worrying thing is not this progressive worsening which, of course, is typical with increasing ISO sensitivity, but the fact that it’s so apparent at the lower ISO settings.
Compared with the Nikon COOLPIX S3000 the Sony Cyber-shot W310 holds its ground pretty well, though we’d say that the COOLPIX has the edge up to 100 ISO. For one thing its better exposure shows a lot more detail in the shadows, but it also shows more detail in the stone column and wood panelling. Beyond that the crops from both cameras exhibit visible noise and supression artifacts.
Finally there’s the Canon IXUS 105 / SD1300 IS which delivers quite a dramatic improvement over the results from either of the other two cameras. Though the 200 ISO crop is slightly softer than the preceding two, at the lower ISO settings the IXUS 105 / SD1300 IS is a clear winner with clean crops showing little if any evidence of noise or processing. It’s not unitl you get to 800 ISO on the Canon that the noise gets the upper hand – providing a range of ISO sensitivities that you can use confidently.
