His artistic approach favoured clarity and historical accuracy. In *The Tattooing of New Zealand*, Pannemaker used fine hatching to document cultural rituals with a clinical eye. His work is distinctive for its use of tonal wood engraving. This technique creates the illusion of soft grey washes using only black ink on white paper. Works like *Discovery of the Remains of Raphael in the Pantheon in Rome* demonstrate his ability to manage large-scale architectural compositions through careful line placement.

Pannemaker prints appeal to modern collectors who value the graphic nature of nineteenth-century illustration. The monochrome compositions provide a clean look for contemporary wall displays. These engravings represent a period when printmaking was both a fine art and a method of historical record. They offer a sense of texture and historical depth that remains relevant for current interior design.
