A portrait is basically the capturing of images showing the likeness of a person or persons where the facial expression and character is predominant.
The following post is a very simple description of several different facial views that may help with your photography.
The front view is the most common portrait view that most people take where the face is in full view and the eyes are looking at or close to the camera. It could be likened to a passport photo view and probably works best with children where their facial expressions tend to be more natural.
The picture of the beautiful bride opposite shows her eyes and nose pointed at the camera. A variation could be a very slight turn of the face or the eyes looking just past the photographers shoulder. The body is usually square to the photographer but as in this case, it can be turned away to highlight the neck and shoulders.
The camera should be focused on both eyes and a shallow depth of field used so only the plane of the face is in focus. Small pocket cameras may not be capable of such a narrow focus range so zooming in on the subject will tend to focus the viewer just on the face.
The background should be uncluttered and preferably out of focus so as not to distract from the subject.
The side or profile view shows only one side of the face and is probably the least used in general photography.
The profile view is best taken with only one side of the face visible so the subject has nice clean lines around the face.
If a part of far side of the face were visible, the portrait photo tends to look less flattering.
With adults, double chins can be a problem and this can partly be fixed by asking the subject to lean slightly forward and stretching the chin slightly forward and upwards but care should be taken not to over do this.
Neck creases can also be a problem particularly if the body is turned at all. You may be able to mask the neck creases with hair or clothing or carefully leaning the body towards the camera while keeping the head upright.
The photo here also has a profile view of the groom with the two-thirds view of the bride.
The most pleasing view is usually the two-thirds view where the face is turned away from the camera at about a 30 degree angle.
The eye closest to the camera should be the center of focus and both eyes fully visible. If the face is turned too far, the nose will cut across the far eye and the photo just wouldn’t fully show the character of the beautiful bride in this case.
This view is my favorite portrait view and works particularly well in this case with the bride focused on the groom during a quiet moment. These sort of moments are the special shots I like to photograph and that the couple will cherish forever.
