Technological breakthroughs are usually as much revelations as revolutions,
satisfying powerful latent demands. Twentieth-century people embraced
mobility, economy, lightness, spontaneity, rapid feedback and sharing with
friends and family. Supplanting earlier miniature cameras, the 21st-century
cell phone camera has delivered all those qualities. Like the Polaroid and
the cheap film camera, it offers a distinctive look that appeals even to some
professionals. And it has also amplified anxieties about photography:
security, privacy, and intellectual property.
