Why you can trust TechRadar
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 produce the graphs below.
For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
This chart indicates that the Canon IXUS 1100 HS's JPEGs have a consistently high dynamic range across the sensitivity range, only overtaken by the Nikon Coolpix S9100 at ISO 1600.
