The light bulb was modeled and rendered in 3D in Autodesk Maya, the fairy is a photograph.
A lot of the hair strands had to be repainted in Photoshop since it was close to impossible to create a hair mask due to the background being a light dusky sky and her hair being so blond.
It turned out really good once all the elements were placed together and composited.
