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 signal to noise ratio
JPEG images from the Samsung NX210 relate the most closely with the Samsung NX200 for signal to noise ratio, and are much better than the Nikon 1. However, from the chart you can see that andOlympus PEN E-P3 and Panasonic G5 have the edge over them overall, while the Sony NEX-5n performs significantly better.
Raw signal to noise ratio
TIFF images (after conversion from raw) from the Samsung NX210 and Samsung NX200 are closely matched for their signal to noise ratio, at the lower end of the sensitivity scale, while it's closer to theNikon 1 at high sensitivities. Results from the Olympus PEN E-P3 and Panasonic G5 aren't vastly different, but again the Sony outperforms the Samsung by quite a considerable margin.
JPEG dynamic range
Our dynamic range results show that there is a drop in performance for the Samsung NX210's JPEG images over the Samsung NX200, with our results in fact putting it behind all the other cameras tested.
Raw dynamic range
This chart indicates that TIFF images (after conversion from raw) from the Samsung NX210 have a greater dynamic range than the Nikon 1 and Samsung NX200's images at lower ISOs, are similar to those from the Olympus PEN E-P3, but they lag behind the results achieved by the Panasonic G5 throughout the sensitivity range, and are significantly behind the Sony NEX-5n.

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.
