Nanjing first became a state capital in 229 AD, when the state of Eastern Wu founded by Sun Quan during the Three Kingdoms period relocated its capital to Jianye (建業), the city extended on the basis of Jinling Yi in 211 AD. Although conquered by the Western Jin dynasty in 280, Nanjing and its neighbouring areas had been well cultivated and developed into one of the commercial, cultural and political centers of China during the rule of East Wu. This city would soon play a vital role in the following centuries.

For digital photo cameras ("digital still cameras"), an exposure index (EI) rating—commonly called ISO setting—is specified by the manufacturer such that the sRGB image files produced by the camera will have a lightness similar to what would be obtained with film of the same EI rating at the same exposure. The usual design is that the camera's parameters for interpreting the sensor data values into sRGB values are fixed, and a number of different EI choices are accommodated by varying the sensor's signal gain in the analog realm, prior to conversion to digital. Some camera designs provide at least some EI choices by adjusting the sensor's signal gain in the digital realm. A few camera designs also provide EI adjustment through a choice of lightness parameters for the interpretation of sensor data values into sRGB; this variation allows different tradeoffs between the range of highlights that can be captured and the amount of noise introduced into the shadow areas of the photo.
How do some camera designs give some EI choices?
by adjusting the sensor's signal gain in the digital realm

Also emerging during this period was New York's no wave movement, a short-lived art and music scene that began in part as a reaction against punk's recycling of traditionalist rock tropes and often reflected an abrasive, confrontational and nihilistic worldview. No wave musicians such as the Contortions, Teenage Jesus and the Jerks, Mars, DNA, Theoretical Girls and Rhys Chatham instead experimented with noise, dissonance and atonality in addition to non-rock styles. The former four groups were included on the Eno-produced No New York compilation, often considered the quintessential testament to the scene. The no wave-affiliated label ZE Records was founded in 1978, and would also produce acclaimed and influential compilations in subsequent years.
