…with your cell phone

You would be surprised how often we get emails from patients asking about this or that. Inevitably we ask them to send in a picture of what they see and inevitably those pictures are blurry.

Cell phones take great intra-oral (tooth) pictures — they have a very small sensor and hence a small aperture to create a deep depth of field (everything stays in focus) and they have the flash very close to the lens. You don’t need an expensive macro photograph rig, but you do need to set up your phone properly.

Open up you camera app.

  • FLASH ON | Whether Android or Apple, make sure to turn FLASH ON (not just AUTO FLASH, it has to be on so that it fires with every shot not just when the phone thinks it’s dark).
  • USE TIMER | Set a timer for 2-3 seconds. This lets you press the shutter button while still having 2-3 seconds to make sure the phone is aimed at your target and stead, and to retract lips or cheeks if need be.
  • ZOOM 4X | Then use you fingers to pinch zoom out to 4X zoom. This should make it so that to get a picture from one corner of the smile to the other your phone will be some 6-8 inches away from the smile.

Press the shutter button to start the timer. Make sure the phone is steady and that you are pulling away cheeks/tongue/etc so that the subject of your shot is visible.
