Canon IXUS 115 HS: Noise and dynamic range
These graphs were produced using data generated by DXO Analyzer. We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO software.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and usually better quality image.
A high dynamic range indicates a better ability to reproduce a wide range of tones. These cameras do not produce raw files, only JPEGs which are automatically processed in-camera to produce the best image possible in the view of the manufacturer.
