I want to lay an 8x10 single weight antique photo in contact with an RC b&w pape r to produce an 8x10 paper negative to make 1 to 1 reproductions. My reason is, I don't want to reduce and then enlarge. I feel I can retain the extreme sharpne ss of the original. I realize my enlarger exposures may be lengthy - exposing th rough the back of the original print to imprint the 'negative' paper. Is the ton al range of paper significantly less than that of fillm? Anybody experienced in this matter?
