We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using DXO Analyzer software to generate the data to produce the graphs below.
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.
JPEG signal to noise ratio
JPEG images from the Nikon Coolpix S9300 show that noise is handled well compared to results from the Nikon Coolpix S9100, Fuji F770 EXR and Sony HX20V, producing the best signal to noise ratio at ISO 200.
This chart indicates that the Nikon Coolpix S9300 compares consistently well against the Fuji F770 EXR at all sensitivities. It produces similar results to the Nikon Coolpix S9100 and Sony HX20V at ISO 200, 800 and 1600, with a dip down almost to the Fuji's level at ISO 400.
