  We present our catalog of U, B, V, and I stellar photometry of the central 64
sq. deg. area of the Large Magellanic Cloud. Internal and external astrometric
and photometric tests using existing optical photometry (U, B, and V from
Massey's bright star catalog and I from the near-infrared sky survey DENIS) are
used to confirm our observational uncertainty estimates. We fit stellar
atmosphere models to the optical data to check the consistency of the
photometry for individual stars across the passbands and to estimate the
line-of-sight extinction. Finally, we use the estimated line-of-sight
extinctions to produce an extinction map across the Large Magellanic Cloud,
confirm the variation of extinction as a function of stellar population, and
produce a simple geometrical model for the extinction as a function of stellar
population.
