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.

For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.

Dynamic range is a measure of the camera's ability to capture a wide brightness range while still retaining detail in the brightest and darkest areas.

JPEG dynamic range analysis: If you shoot JPEG images you're unlikely to see any real difference between these cameras in real-world photography – though the D7100 is right up at the top of the group at the lower ISO settings.

JPEG (converted to TIFF) dynamic range analysis: Nikon DSLRs have developed something of a reputation for dynamic range and the D7100 and D7200 produce their best results when shooting raw files, clearly leading this group up to around ISO 800. Interestingly, in our tests the D7100 proved better than the D7200 at higher ISOs.
