Techniques for measuring the total reddening and extinction through a galaxy are quite limited. For the Magellanic Clouds, it is possible to detect background galaxies in large numbers, so that statistically-significant measurements of the total effects of Magellanic dust are possible. We have used HST WFPC2 images of the LMC to detect background galaxies and to measyre their magnitudes, number density, surface brightnesses and colors. Foreground LMC stars are subtracted from the images by PSF-fitting, leaving only non-stellar images, which include the background galaxies. When compared to control fields away from the LMC, these data can be used to determine the redenning and extinction caused by the LMC interstellar dust. Results of tests on a cluster of galaxies detected near the LMC bar at RA = 5 05, Dec = 69 28 will be shown.
