Peacock

Perhaps to see the structure and not be distracted by the illusions and delusions that color may create? This is the biggest reason why people still do b&w to begin with.

When you see a picture of a peacock, do you expect it to be a certain way? I try not to cater to these assumptions in my work. In some ways, I feel we're trained to expect things in photos like this, and I don't want to spoonfeed that stuff to anybody. Let them look at the photo for what is, and make the decision objectively. That's my thought, anyways. ;)
