For dark tan black magic tan. Show tan intense, beau bronzage ultra dark. Naked tan chocolate: all of them overnight However for photoshoot I never do dark tan. Usually medium. Its all depend when is photoahoot, lighting and photographer on this photos is same day same tan, first had medium and on photoshoot he looks sooo dark, another had light one (he wanted light) and on photos he also looks darker. Problem with too dark tan on photoshoot is that after editing they may looks very brassy.
