These images are a variety of environmental portraits (or perhaps not, depending on your definition of "environmental portrait"). In my view, each of them is a considered portrait (not a snapshot or candid picture) of a person, with an extra component (either background environment, or other detail) that helps to enhance an understanding of the subject ot the portrait.

I also take a very large number of photographs of performers (actors and musicians), and I've made a point of excluding any of those images from this collection of "environmental" portraits.
