There's something special about black and white photography. We cannot help but perceive colour all around us, so the black and white image doesn't capture the world as we see it, but rather, as we remember it.

It is said that we dream in black and white. I don't think that's true. Dreams, like memories, are a non-visual sensation. We might remember some colours that might have stood out, but that's a memory of the experience of colour, not colour itself.

As Andri Cauldwell puts it:

To see in color is a delight for the eye but to see in black and white is a delight for the soul.
