Several methods exist to observe interstellar dust. In this paper, some regions are selected of which optical appearance, like extinction and surface brightness, are discussed, together with a prelimenary comparison of infrared (100 μm ) emission. Careful comparison of extinction, reflection and IR-emission can yield information on the radiative properties of interstellar dust and of the interstellar radiation field.
