Canon ELPH 310 HS / IXUS 230 HS vs ELPH 300 HS / IXUS 220 HS vs ELPH 510 HS / IXUS 1100 HS Noise
The above shot was taken with the the Canon ELPH 310 HS / IXUS 230 HS in Program auto mode. The lens was set to its widest angle 5mm (28mm equivalent) focal length, the sensitivity was set to 100 ISO and the exposure was one second at f3. The crops are taken from the area marked with the red square and presented below at 100%.
The first crop from the ELPH 310 HS / IXUS 230 HS, taken at 100 ISO isn’t completely noise free, but this is nonetheless a perfectly respectable result. There’s good detail in both the column on the left and the wood panelling on the right. There is an overall graininess which you see most clearly in the wood panelling, but it’s not unpleasant in quality and preferable to the smoothness that would almost certainly result from trying to process it out.
At 200 ISO the grain takes on a slightly bitty texture, but you can see almost as much detail in this crop as the previous one. The quality drop from 100 to 200 ISO is fairly marginal and certainly worth the extra stop of exposure it provides. Moving to 400 ISO its a similar story – a slight increase in the noise and another slight loss of detail as a result. The same thing happens at 800 ISO and although the cumulative result is a crop with considerably more noise than at 100 ISO, I’d feel comfortable about using any of these sensitivity settings for photos that were going to be viewed on screen. If I was making full sized prints I might be a bit more circumspect but, even then, the noise at 800 ISO, while abundant, isn’t particularly offensive.
From 1600 ISO on, as you’d expect, the noise gains the upper hand, obscuring ever coarser detail, but it’s good to have a 3200 ISO option for those shots that you’ve absolutlely got to have, regardless of the quality.
Not surprisingly, given that they share the same sensor, the crops from the IXUS 220 HS / ELPH 300 HS and the IXUS 1100 HS / ELPH 510 HS bear more than a passing resemblance to those from the ELPH 310 HS / IXUS 230 HS. They’re not identical, but in the context of quality – how much noise is present at each ISO sensitivity setting and how much image detail suffers as a result – there’s little if anything to choose between them. The most significant difference is that at its maximum aperture of f3.4 the IXUS 1100 HS / ELPH 510 HS has underexposed the 100 ISO shot and the higher ISO shots also look a little underexposed.
All three models offer Handheld Night Scene mode which takes a sequence of shots in low light and produces a single composite image. The ISO is set automatically in this scene mode so it’s difficult to make comparisons, but the results are a definite improvement on what you’d get from a single high ISO shot under the same conditions. The ELPH 310 HS / IXUS 230 HS Handheld Night Scene crop actually looks a little sharper, but this is most likely due to better focussing rather than sensor performance. One of the drawbacks of Handheld Night Scene is that you can only use the default nine area auto focus.
All three models also offer a 3 Megapixel low light mode. As you can see from the crops, as well as higher resolution it provides much better detail with significantly less noise. They also offer a Best Image Selection mode which shoots five shots and chooses the best one.
