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
Raw signal to noise ratio
Nikon's smaller sensor reveals its shortcomings for signal to noise ratio here as the raw files (after conversion to TIFF) are the noisiest of the group.
JPEG dynamic range
The Dynamic range of the JPEG files is respectable, indicating that images have a good range of tones and pleasant contrast.
Raw dynamic range
Dynamic range is quite limited in comparison with the cameras with a larger sensor, but it is still respectable in comparison with the average rugged compact camera.
