Look at the eyes not around the eyes look at the eyes
Ever wondered why so many magazines have faces on the cover? It s because we identify with such pictures, which in turn helps us identify with the magazine. Art editors know that our inclination is to connect with the eyes staring out of the cover, and the same is true of your portraits.
When shooting a person, if only one part of your image is in focus, make it the eyes. That s the first place your audience will look. So long as they re in focus, they ll consider the whole image to be accurately shot, no matter how shallow your depth of field and how blurred the rest of the frame.The eyes are in focus in this shot, so we read it as being accurately focused overall.
