Two absolutely beautiful and very serene videos from Eirik Solheim showing images of the same stand of trees during 2008.
One year in 40 seconds (using 10mm wide angle images):
One year in 2 minutes (using 55mm zoomed-in images):
His Youtube channel has a number of other interesting time lapse or morphing videos, and his personal site offers some background information and details as well as photography tips and tricks. Definitely a new favourite.
