Hello Adrian,

For best results with the photofit you should be 5 to 10 feet from
your subject, so pick your lens appropriately.

You do not need to center the faces perfectly, but the region that you
should center is the 'face region'; from where the chin meets the neck
to half-way up the forehead, and in front of the ears.

If you use just one profile photo Modeller will use the details from
that photo for both sides of the face so there's no need to use 2
profile photos unless you have a specific scar or something that you
want to appear only on the one side.

Lighting is important. For best results use a consumer-style point
flash on the camera for all shots.

Background is not as important, although a dark background may help
with the outer contours.

The marker point positions do not have to be exact, since FaceGen uses
them mainly as a starting point and has tolerance on their
positioning.

The points on the different views do not correspond.

For the frontal points: center of the pupils, the outermost points on
the nose flaps, corners of mouth, outermost points of the cheekbones,
occluding contour of the jaw at the same height as the mouth (or what
would be the same height if the face is tilted up/down).

For the profile points: sellion, nose tip, half way in-between on nose
bridge, outer corner of eye, where nose meets philtrum, forward-most
point of upper lip, forward-most point of lower lip, forward-most
point of chin, part-way (roughly) between chin and neck on lower chin
contour.

Best wishes,
