There are GIFs - and there are the GIFs created by German freelance creative/photographer Nicolas Ritter.
For as you can see, in his series 'One', Ritter has produced GIFs which feature multiple people - but only one of them is animated. The result is really rather wonderful and ever-so slightly spooky:
"The project focuses on the individual in a crowd," writes Ritter about his photos - which were all taken in London, in locations ranging from Buckingham Palace to Liverpool Street Station.
"It particularly imitates the way in which the human eye observes: not viewing a crowd as a crowd, but observing little micro-scenes inside of it."
