CAN you see what’s going on in this stunning picture of blue trees in the snow.
It may look like a painting but this is actually an aerial shot of some trees taken on a snowy day – creating a weird optical illusion.
The incredible shot is one of a series taken by along a street and a river near Sieversdorf in eastern Germany, this week, by photographer Patrick Pleul.
Although it looks like a line of tall trees that have turned a weird shade of blue, on closer inspection you can see the small black trees are throwing the long blue shadows.
So here comes the science bit.
The reason for the striking colour is the fact that snow is white, meaning it reflects all colours.
On a clear day, with snow on the ground, shadows are tinted by the reflection of the sky and the presence of low sun means the blue stands out in stark contrast to the snow.
Another aerial shot of a group of camels walking through the desert recently went viral because of the optical illusion effect of the shadows.
