Dust in Star-Forming Galaxies
  I review the effects of dust obscuration in galaxies at both low and high redshifts, and briefly discuss a method to remove dust reddening from the emerging light of star-forming galaxies. I also analyze the evolution of the dust opacity in galaxies as a function of redshift, and discuss its effect on the observed UV-optical light. The quantitative corrections for dust obscuration given here allow one to recover the intrinsic value of the global star formation at different cosmological times.
