[41-4] Night / 夜間, 2011
The military objectives of the US Air Force Defense Meteorological Satellite Program have created an aesthetic byproduct - a composite photo of the planet, taken during nighttime hours. More than 99% of these representations of actual light sources are indications of human activity on the planet. For example, this image includes more than a million man-made fires, most of them in the Third World, chiefly propagated for agricultural purposes. Population centers are easily identified; however, the amount of light represented here is not necessarily proportional to the population size.
由一系列夜間拍攝所組成的地球合成照片是由美國空軍的國防氣象衛星計劃所衍生出的一美學副產物。這些影像中超過99%的光源都源自於人類在地球上的活動所產生。舉例來說，這個影像含括了超過一百萬個人造火源，大部分分佈於第三世界國家，並且主要用於農業目的。人口分佈的中心點可輕易辨識，不過，在此所呈現的光量並不一定與人口多寡成正比。
