Ah! this explains my confusion. While I was aware of much of what you wrote I for some reason had it in my mind that carbro used the same dichromate sensitizers + non-supercoated bromide paper + some special bleach to achieve the chemical hardening. I must have conflated carbro and ciba for some reason.

Take a normal light and UV photograph of a flower and use normal and UV fluorescing pigmented tissues so that under normal light it displays as the normal light photograph and under UV as the UV.
