Abstract
Three methods of obtaining digital photographs in a clinical setting were compared using direct anthropometry as a reference standard. The methods included a digital camera, scanning negatives from a 35-mm singlelens reflex camera, and scanning Polaroid photographs taken with a Polaroid camera designed for medical documentation. A total of 11 angular and linear anthropometric measurements obtained from 30 healthy volunteers were used for the comparison. The data were analyzed using a variance covariance approach to repeated measures. The analysis revealed that the three cameras were not statistically different from each other. Other advantages and disadvantages, such as cost and ease of use, are discussed. (Plast. Reconstr. Surg. 103: 1819, 1999.)
