This paper presents an in-depth study into how people use their camera phones. Using a combined method of interviews and grounded discussions around a sample of actual photos, the study examined people's intentions at the time of capture and subsequent patterns of use. The result is a 6-part taxonomy describing the way images are used both for sharing and personal use, and for affective and functional use. The implications of these findings for future products and services are discussed.
