At first, British photographer Martin Usborne just wanted to do some reporting on people who leave their dogs locked up in cars. But as he went around scouring parking lots, “making barking noises to try and awaken sleeping dogs that were not actually there,” his project took on a new artistic direction. “The Silence of Dogs in Cars” was inspired by a “childhood memory of waiting in a car whilst his parents were shopping in a supermarket, and the youthful fear that they would not return.”

Meaning “to chase around”, Mekepung was originally designed as a fun game for peasants to spend their free time when the harvest time was ended, as they were waiting for the start of the planting season.

Zed Nelson has photographed the same family, once a year on the same day, for 20 years. I take hundreds of photo’s of my extended family all year round, some just languish on my computer screen unseen by anyone, some get printed, some framed. What is really interesting about this project is not only the obvious time scale but his “ analytical approach“. The same plain background is used for each session and he chooses only 1 frame to represent that years image. My many photographs are a mishmash of family events, his create a family history unfolding . Perhaps less really is more.
