I came across this interesting post of a long exposure photo taken of a tram car in Budapest, that has been lit up with 30,000 LED lights. Itlooks like it is almost invisible in the photo, amazing!
Found on Colossal:
The twinkling lights, when photographed with just the right exposure, creates a marvelling image that resembles a futuristic vehicle speeding through time. This beautiful tradition of decorating trams was an initiative by the Budapest Transport Company, which kicked off in 2009.
Prints of the long exposure images are available from Krisztian Birinyi
