Image Scaling

 

Method 1:

To ensure we make our measurements halfway across the world correctly, we require the subject to measure the length of their mouth (from mouth corner to corner) using a straight ruler. This measurement, once provided to us will allow us to scale the frontal profile image correctly, regardless of the distance from the camera.

Similarly for the side profile image, we require the subject to measure their philtrum length. This is from the tip of the upper lip to the ‘subnasal’ which is where the nose septum just begins. The measurements do not need to be perfectly precise as all the other measurements will all have the same relative error and so faical proportions will still be accurate.

If you are having trouble taking these measurements, send your photos through (assuming they meet the below guidelines) and contact us so that we can provide an alternate method of correctly scaling your image.

Method 2:

If you’re having difficulty with the first method, we can also scale our images using a point of reference in the image such as a ruler or measuring tape. Simply hold the tape or ruler in view at the same distance you are from the camera, in line with your face. This will reduce the likelihood of perspective errors. We can use the increments on the measuring tape to scale our own tools.

Focal Length

The focal length of your shot needs to be taken into consideration. The old saying ‘the camera adds 10 pounds’ has never been truer when considering how higher focal lengths distort your face out laterally.

To ensure accuracy in the image you send, we recommend using default Apple/Android camera settings. The gif on the left exaggerates this effect using high end, professional lenses.

  • 50mm is closest to what our eyes see
  • Iphone X wide angle is a 26mm equivalent
  • Iphone X telephoto is a 52mm equivalent
  • Earlier Iphones use 28-33mm lenses

The facial distortions caused by a few mm of focal length difference is minimal. Taking the photo just like you would for any other is adequate. It’s more important that your photos follow the guidelines below closely.

How to pose

Neutral Head Position

It is crucial for accurate measurements that the subject’s photos are taken from a neutral head position. For most people this should be a neutral eyelevel unless there’s some underlying neck or muscle deformity. This is most easily achieved by trying to look into your eyes from eyelevel in front of a mirror, or levelling your camera to be directly eye level to you. This should feel natural with the teeth held lightly together.

‘NHP’ is important because subjects orient their faces in certain ways, whether consciously or subconsciously to hide what they feel like are their flaws.  For instance those with noticeable asymmetries may tilt their head to one side over another during conversation.

Frontal Profile

For all assessment tiers (preliminary to comprehensive reports) we require at least one frontal profile picture. We recommend standing 1-2m away and zooming in slightly to have the full face in frame, including the ears.

  • Neutral facial expression
  • Neutral head position
  • Regular camera settings (phone camera is fine)
  • Face in clear view with no obstructions
  • Face should take up the majority of the frame
  • Minimal field of view distortion (from being too close to the camera)
  • Simple background such as a wall

Note: We require 1x additional photo with your eyebrows raised to determine where the face ends and the scalp begins (Trichion), especially if you have a receding hairline.

Acceptable (but not perfect)

Neutral head position
Not a neutral facial expression

Unacceptable (neck isn’t neutral)

High resolution
Slight field of view blur (not a big deal)
No hair covering face

Side Profile

For all assessment tiers (preliminary to comprehensive reports) we require at least one side profile picture.

  • Neutral facial expression
  • Neutral head position
  • Regular camera settings (phone camera is fine)
  • Face in clear view with no obstructions
  • Face should take up the majority of the frame
  • Minimal field of view distortion (from being too close to the camera)
  • Simple background such as a wall

Acceptable (but not perfect)

Man's side profile
Neutral head position
Not a neutral facial expression

Unacceptable (neck isn’t neutral)

Model side profile
Jaw can be clearly seen but it’s not a neutral head position
Neutral facial expression
Hair is out of the way

Reference Examples

The images on the right are good examples as they follow all of our given guidelines for a more accurate analysis

Smile profile

This only applies to comprehensive reports which include an additional dentofacial assessment. A picture of the subject in a natural ‘posed’ smile (like for a regular photo) is needed following the same guidelines as before. The mouth area needs to be clear and should not be overexaggerated.

Acceptable

Smile curtain

Ethnicity

In your image submission email, along with all the other requirements, please inform us of your ethnic background to the best of your ability so that we can compare your features against the correct standards and research papers.
