Ready for Your CloseUp

In the movie SunsetBoulevard, Gloria Swanson plays Norma Desmond, a washed-up movie star. In the last scene of the movie, she moves into the camera and says, "All right, Mr. DeMille, I'm ready for my close-up." It certainly is apropos to begin this chapter with that line.

Although the iPhone takes a pretty sharp image of a person close up (see Figure 4.1), it does have a bit of barrel distortion. Barrel distortion is caused by the curvature of the lens. In extreme close-up portraits, it will exaggerate the nose.
