Entertainment and Movie, look no different to my eyes, Sport switches you to a rather cooler colour temperature, while Vivid delivers a similar white point and more saturated colour-balance. Alas, there’s low-latency Game mode but you do get a couple of audio-centric modes – Music and Party – to play with, which do nothing to affect the picture but instead provide preset audio settings.

Archaeologists have found glass beads dating to as early as the third millenium BCE. Glazes based on the same materials and technology date earlier still. But it was in the Late Bronze Age — 1600 to 1200 BCE — that the use of glass seems to have really taken off, in Egypt, Mycenaean Greece and Mesopotamia, also called the Near East (located in what’s now Syria and Iraq).

Pure metallic copper produces a very dark red, opaque glass, which is sometimes used as a substitute for gold in the production of ruby-colored glass.Art from a tomb (top) showsmetal workers using blowpipes to ventilate a small fire during an era that pre-dates Amarna. In an archaeological experiment (bottom), researchers tested whether it was possible to make glass beads like those found at Amarna in a similar manner, blowing into the fire using pipes. a b c Julian Henderson (2013).

The factor △E *ab represents the measurement of distance between any two points in the three-dimensional L*a*b* color space. This enables objective comparison of glass colors without the influence of ambient light or the subjective perception of a human observer. Home theatre enthusiasts will still be served best by opting for an OLED TV like the Sony A80J and combining that with either Sky Q or Sky Stream and a more potent sound system. Early glass was rarely transparent and often contained impurities and imperfections, [21] and is technically faience rather than true glass, which did not appear until the 15th century BC. [26] However, red-orange glass beads excavated from the Indus Valley Civilization dated before 1700 BC (possibly as early as 1900 BC) predate sustained glass production, which appeared around 1600 BC in Mesopotamia and 1500 BC in Egypt. [27] [28] During the Late Bronze Age there was a rapid growth in glassmaking technology in Egypt and Western Asia. [23] Archaeological finds from this period include coloured glass ingots, vessels, and beads. [23] [29] Much early glass production relied on grinding techniques borrowed from stoneworking, such as grinding and carving glass in a cold state. [30]

Unlike today, glass of those times was often opaque and saturated with color, and the source of the silica was crushed quartz pebbles, not sand. Clever ancients figured out how to lower the melting temperature of the crushed quartz to what could be reached in Bronze Age furnaces: They used the ash of desert plants, which contain high levels of salts such as sodium carbonate or bicarbonates. The plants also contain lime — calcium oxide — that made the glass more stable. Ancient glassmakers also added materials that impart color to glass, such as cobalt for dark blue, or lead antimonate for yellow. The ingredients melded in the melt, contributing chemical clues that researchers look for today.

For testing colour accuracy in SDR, we tested a number of modes and found Movie mode best for overall colour performance with an average Delta E of 0.8 – right up there with some of the best TVs we’ve tested.
