Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test.

We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using DXO Analyzer software to generate the data to produce the graphs below.

A high signal to noise ratio (SNR) indicates a cleaner and better quality image.

For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.

Here we compare the Nikon Coolpix L820 with the Olympus SP-820UZ, Sony HX300 and Canon PowerShot SX50 HS.

JPEG signal to noise ratio

Nikon Coolpix L820 review

This graph shows that the Nikon Coolpix L820's JPEG files have significantly stronger signal to noise ratios than JPEGs from the Olympus SP-820UZ and Sony HX300 at every sensitivity setting, but slightly weaker ratios than those found in the Canon PowerShot SX50 HS's JPEGs.

JPEG dynamic range

Nikon Coolpix L820 review

Similarly, the Nikon Coolpix L820's JPEGs have greater dynamic range than the Olympus SP-820UZ and Sony HX300's JPEGs, but weaker dynamic range than the Canon PowerShot SX50 HS's JPEGs at every sensitivity setting. Results here are slightly less spread out than they were for signal to noise ratios, with theSony coming close to the Nikon's scores at ISO 200 and 3200.
