Increase in noise level
In automatic mode, cameras often work in 100 ISO. But even if the available options with these cameras are few, you do have the possibility to manually adjust this parameter to 50 ISO, for example. The image under this setting will always have better definition and be nicer. With all cameras (except for the Panasonic) though, you may be tempted to increase the sensitivity to avoid flash use to have more natural colors and images that better represent the mood. But in increasing sensitivity there are consequences on quality:
Canon Ixus 50
Fujifilm Finepix Z1
Konica Minolta Dimage X60
Nikon Coolpix S1
Below 100 ISO results are always very good. There are a couple of differences, which are quite odd if we consider that all cameras have 5 megapixel 1/2.5’’ sensors. Here you may see the key role of the processor, which lies behind the sensor.
It is even more obvious at 200 ISO. It’s best not to increase sensitivity with some cameras as image quality is so reduced that printing isn’t even possible.
We didn’t evaluate the 400 ISO or greater as all cameras aren’t capable of reaching this level. We’ll let you analyse the noise level.
