My son has paralysis in his right extremities because of cerebral palsey. He uses a small camera upside down, left-handed. Except for flash pictures that have the light source coming slightly from below, he seems to have no other problems. If you can find a camera that works easily one-handed, your friend could perhaps use the same technique.
