What photos look photoshopped but are actually real?

I would like to share some of the photos which may look like Photoshopped but actually its real here.

1. Trees in Schonbrunn Park

2. Salar de Uyuni, the world’s largest salt flat in Bolivia

3. A sculpture in New Zealand designed to look like a cartoon.

4. A sculpture of falling books by Alicia Martin.

5. Hausmannian building Paris during it's renovation in 2007. (A canvas was placed over the building to hide the renovation.)
