Gisson's landscapes, beach scenes, and portraits were intended to create a reflective mood of serenity. His still lifes show Japanese influence in his work, while the French influence is more pronounced in his landscapes, beach scenes and studies of the human figure.
Gisson believed that it is the role of the artist to extend or "explain" perception and feeling and in this way enlarge the total human vision...."Flowers for me are a way of feeling certain effects of light and conversely, light is a means for expressing something very personal about the way I experience flowers."
"When I begin to paint, certain remembered sensations
come to me and it is these that I translate into visual form
and related subjects. These subjects-- people, the nude, florals,
landscapes, beaches, etc., recur constantly like obsessive
memories. For the most part they are the common universal experiences
of all of us, neither contemporary nor out of an antique past,
but with a sentiment which I hope is recognizable to others
at any time."
