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 P600 with the Nikon P520, Sony HX400v and Panasonic FZ72.
JPEG signal to noise ratio
In terms of signal to noise ratio, the P600 doesn't fare particularly well, coming bottom at almost every sensitivity from ISO 200 onwards. It is also beaten by the P520, the camera's predecessor. This could be indicative of an increase in detail resolution at the expense of introducing noise though. It is the Sony HX400V which is perhaps the best performer, especially at the higher end of the sensitivity scale.
JPEG dynamic range
In terms of dynamic range, as we might expect, the P600 is very similar to its predecessor, the P520, matching it pretty closely across the sensitivity range. it is beaten at every sensitivity by the Panasonic FZ72 however.
