You and Your Rapport
This is not a photographic term, as one may call the others, but rather is an important supporting virtue to have if you intend on taking portraits. In my opinion, it is best to establish a rapport with your subject before you proceed to take a photo.
It puts them at ease and the expressions that you get and genuine.
And, it also helps you to know, who can help you produce the shot that you want.
The above photo needed to have someone with a super expressive eyes, and knowing Gowri, I knew she was the perfect choice.
Even if you are shooting someone new, for the first time, take a moment, talk to the person, and then take the shot, makes things easy.
In the last series, Y was for You.
