A photographer is using a unique method to show the shift from day to night across famous cities in spectacular images. Daniel Marker-Moors' take on time-lapse photography – which he calls time slice – sees the photographer snap image after image, before combining them to create beautiful, vibrant works. His images usually focus on a point in the day with the most dramatic change in light, such as sunrise or sunset. Marker-Moors, from Los Angeles, begins by shooting hundreds and sometimes thousands of images from the same spot. Here: Chicago – 35 photographs, 15 minutes.

Broadway Tower is a folly located on Broadway Hill, near the village of Broadway, in the English county of Worcestershire, at the second highest point of the Cotswolds after Cleeve Hill. Broadway Tower's base is 1,024 feet (312 metres) above sea level. The tower itself stands 55 feet (17 metres) high. The “Saxon” tower was designed by James Wyatt in 1794 in the form of a castle, and built for Lady Coventry in 1799. The tower was built on a “beacon” hill, where beacons were lit on special occasions. Lady Coventry wondered if a beacon on this hill could be seen from her house in Worcester – approximately 22 miles (35 km) away – and sponsored the construction of the folly to find out. The beacon could be seen clearly.

Elio Angulo (bottom C) lies inside a cardboard coffin next to Alejandro Blanchard as they introduce their product to potential customers at a mortuary in Valencia, in the state of Carabobo, Venezuela August 25, 2016. When Venezuelan entrepreneurs Alejandro Blanchard and Elio Angulo decided to create cardboard coffins, they were looking for an ecological selling point to compete against classic wood and brass caskets. Three years on, with the oil-rich country mired in deep economic crisis, their “bio-coffins” are becoming a viable option because of high prices for wooden coffins and shortages of brass ones.

Shoppers wrestle over a television as they compete to purchase retail items on “Black Friday” at an Asda superstore in Wembley, north London November 28, 2014. Britain's high streets, malls and online sites were awash with discounts on Friday as more retailers than ever embraced U.S.-style “Black Friday” promotions, seeking to kickstart trading in the key Christmas period. In the United States the Friday following the Thanksgiving Day holiday is called Black Friday because spending usually surges and indicates the point at which American retailers begin to turn a profit for the year, or go “into the black”.

Others point to a tree with mystical significance for locals. And maybe it's just chance.
