Ian Curtis/Sam Riely

The lighting when Ian Curtis is in a room on his own is very isolated, there is one point of light, which is normally a lamp that provides lighting for a section of the room, which adds a lot of shade to the face. the single light and the large headspace within the film, which is a running theme, shows isolation, and that he feels small, his face is very washed out, and the shots are minimal with very little in them, so the center thing your look at is the character and the lighting.
