Gauthier looks to her immediate surroundings for her subject matter, primarily florals, still life and landscape imagery. She achieves a unique atmosphere in her work by hand painting traditional gelatin silver prints with oil based pigments and wax, imbuing the black and white images with warm umber and sienna tones and adding subtle texture to the surface. Through this unique process, Gauthier captures more than a still life or a landscape, but an atmospheric mood that is unique to her body of work.
