Resolution charts

As part of our image quality testing for the Nikon Coolpix S4150, we've shot our resolution chart.

If you view our crops of the resolution chart's central section at 100% (or Actual Pixels) you will see that, for example, at ISO 100 the Nikon Coolpix S4150 is capable of resolving up to around 20 (line widths per picture height x100) in its highest quality JPEG files.

Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:

Noise and dynamic range

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.
