Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test.
We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO Analyzer software to generate the data to create these graphs.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
JPEG images from the Canon IXUS 230 HS have a good consistent signal to noise ratio throughout the sensitivity range, with the results closely relating to the Nikon Coolpix S8200 upto ISO 1600.
Dynamic range
This chart indicates that the Canon IXUS 230 HS's JPEGs dynamic range results are consistently high beating the Samsung PL170, Nikon Coolpix S8200 and Panasonic Lumix DMC-FS22. This shows that the Canon IXUS 230 HS is capible of resolving a higher than average amount of shadow and highlight detail across the sensitivity range.
