Prints sizes range from 40 x 50 to 60 x 80 cm. (16 x 18 to 24 x 30 inches).

Two means of printing are used: gelatin-silver and charcoal. Stewart makes his own gelatin-silver prints, but entrusts the charcoal to the Fresson laboratory close to Paris. Charcoal printing is a 19th century technique whereby pure pigments are embedded in the gelatin base, so producing an unequalled chromatism and richness.

It’s a slow and delicate process (two days are needed to make a print) but admirably suited to much of Stewart's images.

Occasionally Stewart turns to a variety of media (acrylic paint, pencil or Photoshop).
Prints are signed and numbered, most often in editions of 25.
