This peaceful view of Edinburgh, Scotland, at twilight, was captured by Singaporean photographer Cheng Kiang Ng. He did so by blending two exposures – one for the highlights and another for the shadows – together to approximate what the human eye would have seen. Some modern digital cameras will do that for us automatically, if we ask. Quite often overdone and unnatural looking, this new form of photography is called High Dynamic Range (or HDR).
The monument on Calton Hill, on the left, was built in 1831 to honor the 17th-century Scottish mathematician and philosopher Dugald Stewart. Known for his essays and dissertations on moral and metaphysical philosophy, he would certainly be pleased with its auspicious location.
