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
The Samsung NX Mini puts in a consistent performance for JPEG signal to noise ratio. Although it's not the best performing camera on test - that accolade goes to the Sony RX100 II, it's a decent overall performance. At the higher end of the sensitivity scale, the NX Mini performs much better than the Nikon S1.
Raw signal to noise ratio
In terms of the raw format files (after conversion to TIFF), the Samsung NX Mini again puts in a reasonably consistent performance across the sensitivity range. It is beaten at the lower end of the scale by the Panasonic GM1 - but it's worth noting that the GM1 has a much larger sensor. It is actually very closely matched by the Sony RX100 II, and beats the Nikon S1, but not by much.
JPEG dynamic range
For dynamic range, JPEG files appear to put in a poor performance when compared with the other cameras on the test - here we can see that throughout most of the sensitivity range it is the Nikon S1 which performs significantly better. The Samsung NX Mini in fact competes most closely with the Sony RX100 II.
Raw dynamic range
In terms of raw format files (after conversion to TIFF), the Samsung NX Mini actually performs much better, putting in a consistent performance across the sensitivity range. It is beaten by the Panasonic GM1 right up until ISO 6400. It performs better than the Sony RX100 II and the Nikon S1 though.

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.
