01. Frame Your Subject
Framing is a technique where by you draw attention to one element of an image by framing it with another element of the image. Framing gives an image depth and draws the eye to a point of interest in the image.
You could do it by placing your subject in a window or doorway, have them look through a small gap or even use their hands around their face. See more examples framing in photography here.
02. Go with a Wide Angle
Shooting with a wide angle lens attached to your camera can help create some memorable shots when you’re doing portrait photography.
At very wide focal lengths you can create some wonderful distortion. It might not be the type of shot you take of your wife or girlfriend (unless she’s in a playful mood) but using these focal lengths will enlarge parts of the face or body that are on the edge of the frame more than what is in the centre.
It can also give a wide open and dramatic impact when your subject is in an impressive setting.
