The authors present a detailed study of the extinction and the reddening towards the three compact H II regions Sh 2-152, Sh 2-156, and Sh 2-269. In each of these objects, large amounts of dust are found in the vicinity of ionization fronts. On the whole, Galactic H II regions and giant extragalactic H II regions occupy distinct zones in the extinction-reddening plot: whereas for giant extragalactic H II regions the extinction is higher than expected from the reddening, assuming uniform foreground dust i.e. "interstellar extinction", for Galactic H II regions the extinction is equal to or smaller than that expected from the reddening. It is suggested that the large amounts of dust situated in the associated molecular clouds, behind the observed galactic nebulae, may be partly responsible for this situation.
