We present a new method, based on surface photometry, which allows one to make the spatial resolution of extinction maps of dark clouds as fine as necessary. Applying this technique to the Coalsack (l = 302°, b = 0°), we derived an extinction map and the dust mass MD = (62 ± 25) M⊙. The density was found to vary ρ ~ r−0.8, typical for stable clouds.
