These graphs were produced using data generated by DXO Analyzer.
We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO software.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
JPEG images from the Sony Cyber-shot HX100V show less noise than both the Panasonic FZ48 and Canon Powershot SX30 IS up to a sensitivity of ISO 400
This chart indicates that the Sony Cyber-shot HX100V JPEGs have at least a 0.5EV higher dynamic range than the Panasonic FZ48's JPEG files up to a sensitivity of ISO 800.
