3. Does "re-epidermalisation" somehow imply "revision in the way the black body is viewed and understood"?

4. Does "black body as a ‘light sensitive “frame” or “screen”" mean "black body as a context and basis like canvas for a painting"?

Context:

Hall describes 1990s black art as a ‘re-working of the abjected black body through desire’. This black narcissus would produce new corporeal schemas which rewrite the self using the black body as a ‘light sensitive “frame” or “screen”’ for a re-epidermalisation. Already in this description there is a hint of the importance of photography to this politics of representation – in the sense that, as the technique of analogue photography positivises the negative, so too would these new images of the black body. A key exhibition in London’s ICA in 1997, Mirage, extended the notion of what this re-epidermalisation might mean, not simply as political correctness, but as an interrogation of the internalised fantasies of blackness that circulate in both white and black culture as a result of incorporating the oppressor’s gaze (Art and Psychoanalysis by Maria Walsh).?
