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.
Here we compare the Nikon Coolpix S6300 with the Nikon S6400, Sony W690 and Panasonic FS45.
JPEG signal to noise ratio
These results show that the Nikon Coolpix S6300's JPEG files have a stronger signal to noise ratio than those from the Nikon S6400, Sony W690 and Panasonic FS45, throughout the sensitivity range. The Sony produces the second best results at ISO 200-400, before tailing off later. The Panasonic is the next best, while the Nikon S6400 is the least impressive.
JPEG dynamic range
In terms of dynamic range, JPEGs from the Nikon Coolpix S6300 are again the strongest. Again, the Sony W690 produces similarly strong results at ISO 200-400, before tailing off. This time the Nikon S6400 is the nest strongest, and the Panasonic FS45 is weakest.
