Abstract
We discuss the problem of a consistent determination of the visual extincti on to objects in and behind a dark cloud. The use of near-infrared colours is discussed, in particular the H-R colours. We concentrate on the uncertai nties, with emphasis on the extinction law and on the intrinsic colours of the young stars embedded in a dark cloud. The cases of the two intensively studied nearby star-forming clouds, Taurus and Ophiuchus, are addressed.
