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 better quality image.
JPEG images from the Canon Powershot SX30 IS have a lower signal to noise ratio than comparable cameras across the sensitivity range.
This chart indicates that the Canon Powershot SX30 IS's dynamic range is higher than all but the Sony HX100V up to a sensitivity of ISO 400, where it falls offsteeply.
