We study photon diffusion in a one-dimensional model foam composed of thin films and Plateau borders. Each thin film or Plateau border is characterized by its own intensity transmittance. We relate l(Foam), the transport-mean-free path of photons diffusing in the foam, to the foam microstructure. Denoting by l(Film) (l(PB)) the transport-mean-free path of photons in a medium composed only of thin films (Plateau borders), we find 1/l(Foam)=φ(F)/l(Film)+φ(P)/l(PB). Here φ(F) and φ(P)=1-φ(F) are the fraction of films and Plateau borders, respectively.
