Anatomical DIY filter

Here is my input to this week's Experimental Photography challenge: DIY filters. Took the shot in Rauhaniemi at the golden hour. In the background is the lake Näsijärvi still covered with ice.  (We even saw two people skating on the ice!). Very cold wind blew from the north. 
In front of the camera lens is a transparent sheet of my Human Physiology and Anatomy book. (When my son was small he was super interested of the book).

A view without the filter can be seen as an extra photo.
