Silver mirror toned prints of the Supertrees at Gardens by the Bay, Singapore—where direct toning turns the sky to metal and the print imitates its subject

Taking a silver mirror toning recipe tuned for black and white RC paper onto fibre, lith prints, RA-4 colour paper, and mordançage—and finding where it breaks

The photochemistry and physics of silver mirror toning—physical development, nucleation at the emulsion surface, and the percolation threshold where scattered colour becomes a mirror

Deliberately inducing the silver mirroring that conservators spend their careers preventing—the process, the chemistry, and the two directions it can run
