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.
Signal to noise ratio
JPEG images from the Fuji FinePix F600 EXR (without EXR) show a good signal to noise ratio up to a sensitivity of ISO 800, despite this the Canon IXUS 220 HS, Nikon Coolpix S9100 and Panasonic Lumix DMC-TZ20 all have better results from around ISO 200.
This chart indicates that the Fuji FinePix F600 EXR's JPEGs (without EXR) only just beat the Nikon Coolpix S9100 at ISO 200, at sensitivities above this the Canon IXUS 220 HS, Nikon Coolpix S9100 and Panasonic Lumix DMC-TZ20 greater dynamic range results.
