Practical Guide to Dental Photography

Extra Oral Views
Set up-positioning of Photographer

For the best result of extra oral views, the camera should be positioned parallel to the patient at a constant distance of approximately l .5m.

Godox MF-R76 S plus Dental Ring Flash - Set up-positioning of
Photographer

The camera aperture should be set to f/8. Autofocus can be used as manual focussing can be difficult when holding the camera in the portrait position. Autofocus is activated by moving the AF switch on the lens to the AF position.

Intra Oral Views

Intra oral views are typically taken whilst the patient is in the dental chair as this simplifies the positioning of the patient and photographer for some of the standard views. Make sure to keep the lens set to manual focus and follow the guidance for each view to set the focus distance and the aperture correctly. Using manual focus will ensure that photos taken at different stages of treatment can be easily compared to show progress.
