Carbon, also called carbon transfer, is one of the most beautiful of all photographic processes. Invented in the mid 1860s carbon prints have an image that consists of a pigment encapsulated in a uniform layer of hardened gelatin. This structures gives carbon prints a highly surface relief with true three-dimensional quality, a look that is unique among all photographic printmaking processes.
Some of my monochorome work is printed with archival pigment prints. For this work I replace the color inks in a printer with a special set of inks that has seven shades of black, K7 Piezography. The seven shades of black assures higher detail and definition with a smoother tonal scale than when making monochrome prints with color ink sets that contain only two or three shades of black.
