Foundations of Portrait Composition Part I: Framing Your Model
Summary
The trouble here is that the typical basic lens is around 30 mm, which means a rather wide angle of view (note that this focal length and the others mentioned here are stated as full-frame equivalents). If you take this kind of lens and use it for a “head and shoulders” photo without including any of your model’s surroundings in the picture, the wide angle will force you to step up very close to your subject. The human eye doesn’t even register it, but a camera will ruthlessly capture an enlarged nose, chubby cheeks, and a rounder look for the head overall. To put it simply, your subject should be one third of the way into the frame in terms of width (from its right or left) and height (from its top or bottom). One typical basic mistake is to put the head halfway from the bottom, leaving lots of empty space at the top.
