The technique used in Natalie Corman's paintings is called "Cloisonné".  It involves manipulating a photograph in a computer program, adjusting light and contrast, crop, skewing etc. and then separating it into 8-12 shades, depending on the desired effect. The resulting image is then projected onto a canvas and traced  in pencil. The pencil lines are accentuated with diluted caulking to make them stand out.  The artist then decides on  a pallet of colours, often monochromatic,  and mixes these using liquid acrylics. The paint is then poured into each island separately using small bottles.
