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 Samsung MV800 are on a par with those from the Fujifilm Finepix 550 EXR up to ISO 400. From this value the MV800 overtakes producing a better signal to noise ratio up to around ISO 1600.
This chart indicates that the Samsung MV800's JPEGs have a consistently lower dynamic range result than the Canon IXUS 220 HS, Nikon Coolpix S9100 and Fujifilm Finepix 550 EXR, showing the shadow and highlight tone is easily lost.

Amy has been writing about cameras, photography and associated tech since 2009. Amy was once part of the photography testing team for Future Publishing working across TechRadar, Digital Camera, PhotoPlus, N Photo and Photography Week. For her photography, she has won awards and has been exhibited. She often partakes in unusual projects - including one intense year where she used a different camera every single day. Amy is currently the Features Editor at Amateur Photographer magazine, and in her increasingly little spare time works across a number of high-profile publications including Wired, Stuff, Digital Camera World, Expert Reviews, and just a little off-tangent, PetsRadar.
