Most photographs ever made are not art. They are records: birthdays, vacations, faces of people who mattered to someone.
Vernacular photography — the snapshot, the family album, the accidental image — has its own aesthetic that professional photography often struggles to imitate. The blurriness, the cropping accidents, the red-eye: these are not mistakes but markers of a particular mode of attention.
Photographers like Martin Parr and Wolfgang Tillmans have absorbed vernacular aesthetics deliberately. The result is work that looks effortless because it has internalized constraints that "correct" photography works hard to avoid.
