title: [Investigation about particularity of dental clinical digital photography].
abstract: Dental photography is one of the special field in photography because of the particularity of the technology and approach. Lack of depth of field is one of the most possible problems for new learners. In dental photography, the control of depth of field depends on aperture only, deep depth of field can be achieved by decreasing the aperture. The parameters of exposure include aperture, shutter speed, flash intensity and ISO, which control the exposure together. The area of pictures is controlled by proportion, with manual exposure for getting right exposure. Manual focusing is suggested instead of auto focusing. The appropriate technology, method and right area are the most important factors for dental photography, and later treatment has to be avoided.
