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.
JPEG images from the Panasonic Lumix DMC-FX90 are on a par with those from the Nikon Coolpix S9100, but has the advantage of a lower minimum sensitivity of ISO 100.
Dynamic range
This chart indicates that the Panasonic Lumix DMC-FX90's JPEGs are on a par with the Canon IXUS 230 HS. Whilst the Fujifilm Finepix F550 EXR has a better dynamic range at lower sensitivities the Panasonic FX90 captures a more consistant tonal range throughout the sensitivity settings.
