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 Samsung ST6500 are on a par with those from the comparison cameras throughout the sensitivity range.
This chart indicates that the Samsung ST6500's JPEGs have a high dynamic range at low sensitivities. As the sensitivity increases above ISO 200 the dynamic range falls dramatically.
