“Find a location with good light for a portrait shot. Place your subject some distance in front of a simple background and select a wide aperture together with a moderately long focal length such as 100mm on a 35mm full-frame camera (about 65mm on a cropped-frame camera). Take a viewpoint about one and a half metres from your subject, allowing you to compose a headshot comfortably within the frame. Focus on the eyes and take the shot.”
I have used an archive shot for this; as,this something that I practise a lot with my portraits (plus I was struggling finding a willing volunteer).
100mm at f2.8 on full frame
The shallow depth of field has lifted the subject from the background.
