  We detail a technique for estimating the UV extinction and luminosity of UV
selected galaxies using UV quantities alone. The technique is based on a tight
correlation between the ratios of far infrared (FIR) to UV flux ratios and UV
color for a sample of local starbursts. A simple empirical fit to this
correlation can be used to estimate UV extinction as a function of color. This
method is applied to a sample of Lyman-break systems selected from the HDF and
having $z \approx 3$. The resultant UV emissivity is at least nine times higher
than the original Madau et al. (1996) estimate. This technique can be readily
applied to other rest-frame UV surveys.
