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 Fuji FinePix F770 EXR with the Fuji FinePix F600 EXR, Canon PowerShot SX260 HS and Panasonic Lumix TZ-30.
Signal to noise ratio
These results show that the JPEG files from the Fuji FinePix F770 EXR have a lower signal to noise ratio than those from the Fuji FinePix F600 EXR, Canon PowerShot SX260 HS and Panasonic Lumix TZ-30 at almost every sensitivity, with results closest in quality to the Fuji F600 EXR.
Dynamic range
Again, the Fuji FinePix F770 EXR shows less dynamic range in its JPEG images than the Fuji FinePix F600 EXR, Canon PowerShot SX260 HS and Panasonic Lumix TZ-30. The difference is most pronounced with the Canon and Panasonic, while the Fuji F600 EXR's images are the most similar, although still better.
