Some GIMP magic
(This is a reprint of the original post)
A year ago, I posted about one of my photos, picturing a large bridge in a beautiful landscape. That photo was taken on June 2005, and it shows the reservoir created by the Barrios de Luna dam at its full capacity. This year, instead, we had a very dry season, and the reservoir is almost empty now. A few days ago, I took another photograph from the same location. With a bit of GIMP magic (available even to inexpert users like me), I made a composition showing the two different extreme states of the artificial lake. It is very notable the huge difference in size between the two bridges.
