- Shutter Speed – A speed of 1/100 to 1/160 is generally fast enough to capture clear images without blurring.
- ISO – A lower ISO setting (100-200) reduces noise and ensures clear images, which is particularly important for capturing detail.
Patient Positioning
Ensure the patient is seated comfortably in the dental chair and positioned at an angle that allows for easy access to the area being photographed. Clear instructions and a gentle approach with retractors help the patient stay comfortable.
Lighting Techniques
- Avoid Overexposure – Use diffusers or lower flash power to prevent reflective surfaces, such as enamel, from becoming overexposed.
- Shadow Control – If using a twin flash, adjust each flash angle slightly to highlight different aspects of the teeth and gums without creating harsh shadows.
Focus and Composition
- Manual Focus – For close-up shots, manual focus is recommended to ensure precise clarity on the area of interest.
- Framing – Carefully frame the shot to include all relevant details, such as the entire tooth surface or full arch, depending on the purpose of the image.
Preparing the Mouth for Photography
Clean the patient’s mouth by asking them to brush and rinse, ensuring surfaces are clear of any food particles or debris. Lip balm can be used to prevent lips from appearing dry in the images.
