How to take a good photo
Image quality directly affects analysis accuracy. Follow these steps for the best result.
1
Good lighting is essential
Use natural light or a bright lamp. Avoid dark rooms. The oral cavity must be clearly visible.

Use a mirror to position yourself. Keep the camera 15–20 cm from the lesion. Avoid blurry shots.

Focus on the lesion
Tap the lesion on screen to focus. The area of concern should fill at least 40% of the frame.
