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 dynamic range
This chart shows that the Panasonic 3D 1 compares closely with the Sony HX9v and captures a wide tonal graduation in the shadows and highlights up to a sensitivity of ISO 800. Above this sensitivity, although the dynamic range drops, images are still usable.
