Standardized portrait photography for dental patients.
Photography is becoming an increasingly important tool in the dental profession. But documentation of orthodontic or orthognathic treatment with pretreatment and posttreatment photographs can be misleading if features on one or both photographs are distorted. The dental photographer must be constantly aware of the importance of standardizing photographic variables when documentation of change is important. Although total reproducibility may not be practical, the photographer can establish a reasonably standardized approach to photographing patients. In this article the authors present the major considerations for frontal and profile facial photographs. Lens selection, camera position, subject distance, and position are all variables to be understood and controlled if accurate reproduction is desired. Numerous frontal and lateral photographs were made with head position, camera position, jaw position, and lens focal length changed to allow assessment of their contribution to the final picture. Using easily recognized facial landmarks, dental photographers can standardize frontal and lateral portraits for more consistent comparison.
