Reflecting Houses
I don't think it is possible to straighten a photo of houses in Amsterdam.
Many of them are leaning forward and were built that way on purpose.
They are very narrow and tall and when they move furniture they do it from outside.
There are hooks at the tops of many homes and they pull the furniture up that way.
If the house is leaning forward then they don't damage it when they move the furniture.
