Bill Brandt. Nude

Bondage and...that's about it, apparently (?) 
I would say that there is more to it. I would say that we are dealing with an enciphered photo that is tempting us to search for (a) certain meaning (s)
The components are within our reach: nude, white, black. The black present in the pubian area takes the sexuality of the frame one step further in an explicit way whilst the white of the skin induces me the feeling of undiscovered areas.
The black is invading the white but it is not a sudden invasion but more like an insidious one. 
The sexual black is invading the white through that cord wrapping the woman's body and even her face which is entirely covered. 
What does this say to me ? Perhaps that the woman is a victim of its own sexuality or of a sexuality projected from outside. Or most likely.
