I printed some of my photographs via a black-n-white digital printer onto coloured sheets of paper. Grabbed a sharp, shiny, stainless steel scalpel and chopped ’em all up. Then recombined them and used spray adhesive to stick them together.
My skills as a cut-n-paste artist with hot wax and bromides are still useful.
Oh for the good old days, when times (new roman typesetting stencil transfer sheets) were bad 😉
