| Frank Tenney Johnson
Johnson was a master of the nocturne painting and he refined his own special technique for the genre. Johnson primed his canvases with a chalk-white base mixed with a portion of vermilion or Spanish red. After he had completed the under painting, he put the canvases aside for a period of a year or more to set. The entire process was said to have accounted for the depth and luminosity of Johnson's finished works.
