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 Panasonic TZ-30 have a lower signal to noise ratio than the Fujifilm F600 EXR and Olympus SP-620 UZ at the lower end of the sensitivity scale. At the top end of the sensitivity scale the TZ-30 shows good noise performance for low light conditions producing similar results to the Samsung WB750.
This chart indicates that the Panasonic TZ-30 is capable of capturing a good tonal gradation in the shadows and highlights across the sensitivity range, out-performing all but the Samsung WB750.
