We present UBV photometry of the eclipsing binary Harvard Variable 2274 in the Large Magellanic Cloud (LMC). The stellar parameters of
this binary system were recently calculated by Guinan et al., who gave both a reddening toward HV 2274 of E(B-V)=0.083+/-0.006 and a
distance modulus to the LMC of &mu;LMC=18.42+/-0.07. The reddening of this system was also determined by Udalski et al., who found
E(B-V)=0.149+/-0.015. With Udalski et al. B and V photometry, Guinan et al. obtained E(B-V)=0.12+/-0.009 and &mu;LMC=18.30+/-0.07.
Using our UBV photometry, we derive a reddening of E(B-V)=0.088+/-0.023, consistent with the original value of Guinan et al. and
supporting a longer distance modulus to the LMC of about &mu;LMC=18.40+/-0.07. We stress the uncertainties inherent in ground-based
UBV photometry and the concomitant uncertainties in determining distances based upon such photometry.
