I have always viewed portraiture as the most difficult of the photographic genres, so I generally avoided it for decades.  However, this changed in 2020 when I read Walter Isaacson's biography of Leonardo da Vinci, who tried to capture in his portraits the sitter's inner feelings and secrets.  He went so far as to dissect cadavers to study the innervation of facial and body muscles to try to understand how our inner emotions manifest in our physical bodies through gesture and facial expression.  The subtle outward expressions of inner feelings is what I am trying to achieve with my portraiture work - anamnesis.
