We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO software to generate the data to produce the graphs below.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
JPEG images from the Nikon Coolpix S1200pj are a little below those from the Nikon Coolpix S4150, Samsung ST95, up to around ISO 400 where it takes a step up and is slightly better than the Canon PowerShot A3200.
This chart indicates that the Nikon Coolpix S1200pj's JPEGs just have the edge over the Samsung ST95 from ISO 200 and show a good, but not outstanding dynamic range performance throughout the sensitivity range. Its performance is consistently better than that of the Nikon Coolpix S4150.
