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 F900 with the Fuji F800, Canon S110 and Nikon P330.
JPEG signal to noise ratio
As we can see from this graph, the Fuji F900's JPEG images contain weaker signal to noise ratios than JPEGs from the Nikon P330 at every sensitivity setting, and weaker than the Canon S110 at every sensitivity except ISO 6400. The Fuji F900's JPEGs contain similar signal to noise ratios to the Fuji F800's, with the F900's coming out slightly stronger at ISO 100 and 6400, pretty much the same at ISO 400 and a little weaker at other sensitivities.
Raw signal to noise ratio
The Fuji F900's TIFF images (after conversion from raw) are again not as impressive as the Fuji F800's, containing weaker signal to noise ratios at every sensitivity except ISO 3200, where the two cameras' TIFFs perform almost identically. The Fuji F900's TIFFs contain weaker signal to noise ratios than the Canon S110's at every sensitivity setting. The Fuji F900's TIFFs show stronger ratios than the Nikon P330's TIFFs at ISO 100-400, but at ISO 800-3200 the Nikon's TIFFs are stronger.
JPEG dynamic range
Again, the Fuji F900's JPEGs aren't the most impressive of the group, showing significantly less dynamic range than the Fuji F800's JPEGs at every sensitivity except ISO 100, 6400 and 12800. The Fuji F900's JPEGs also contain less dynamic range than the Canon S110 and Nikon P330's JPEGs at every sensitivity setting except ISO 100.
Raw dynamic range
This chart indicates that TIFF images (after conversion from raw) from the Fuji F900 contain greater dynamic range than the Fuji F800 and Nikon P330's TIFFs at ISO 100-400, but are weaker at ISO 800-3200. Similarly, the Fuji F900's TIFFs have slightly stronger dynamic ranges than the Canon S110's at ISO 100-200, but are weaker at ISO 400 and above.
