Review: Nikon Coolpix S2500

Nikon Coolpix S2500
Our test is now underway, but we've already completed our resolution, noise and dynamic range tests, the results of which we would like to share with you here.

Nikon's Coolpix S2500 has point-and-shoot simplicity, but houses clever technology such as Smart Portrait mode, Vibration Reduction, Best Shot Selector and Blink Detection to help you get the best results in a wide range of situations.

Nikon Coolpix S2500: Image quality and resolution
As part of our test we shoot our resolution chart at every sensitivity setting.

The higher the value quoted in the caption score, the greater the level of detail being resolved and the better the image quality.

Nikon Coolpix S2500: 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.

Dynamic range
A high dynamic range indicates a better ability to reproduce a wide range of tones.
These cameras do not produce raw files, only JPEGs which are automatically processed in-camera to produce the best image possible in the view of the manufacturer.
