Most Expensive Photos ever sold!

This is kinda intersting I think...check out the most expensive pics ever sold. I like this 

Gustave Le Gray’s “The Great Wave, Sete”


It was sold for  "only" $838,000 in 1999...but there is an interesting story.
"Le Gray’s image marked the first time that a photographer had managed to expose landscape and sky correctly in the same image. He did this by creating one negative for the sky and one for the sea, and printing them together on the same sheet of paper. In effect, he created a collage." (Photopreneur)
