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 Samsung ST95 show that whilst the Signal to Noise ratio is better than the Nikon Coolpix S3100, results across the sensitivity range areconsistentlylower than both the Canon Powershot A3300 IS and Panasonic Lumix DMC-FS18

This chart indicates that the Samsung ST95's JPEGs dynamic range is fairly low and it drops dramatically at sensitivity values higher than ISO 200.
