A portrait can be many things to many people.
For me, a portrait needs to include the environment,
for a person's surroundings speak worlds of information about the sitter.
Using my 5x7 inch wooden Kodak
ensures that every inch of the surroundings will be in focus;
and stopping down to f45 and opening the shutter for several seconds or even minutes
means that the sitter is likely to be a bit soft.
For me, the softness allows the inner person to be seen,
a vision of the ageless spirit we all have inside us.
