Glass causes a major threat to birds due to its transparency and reflectivity. When vegetation is reflected in the glass, birds are not able to distinguish between a real tree and its image. There is a solution for this: certain patterns on windows can help to prevent birds from flying into the windows. I was commissioned by Martin Rössler, one of the leading researchers in this field to photograph over 60 panes of glass with different bird friendly patterns on it! What a challenge! After some discussions we decided to work in the studio, so as to have a controlled light setting. This forced us to use a wallpaper in order to simulate nature.  Have a look behind the scenes!
