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 Sony HX200V show good signal to noise ratio results, however the improved results after ISO 3200 comes at the cost of detail, which is smoothed in-camera to reduce noise.
