The NASA SWIFT mission contains both a Gamma ray and UV-optical (UV/OT) telescope to monitor the flux variations of Gamma Ray bright objects. Blazars are among some of the brightest Gamm Ray objects in the sky. I have mined the SWIFT UV/OT telescope archive and produced optical light curves of 5 TeV Blazars: Mkn 421, MKN 501, PKS 2155-304, 1ES 1959+650 and 1ES 2344+514. I have tested 3 different reduction techniques: the standard processing provided by the SWIFT mission software, differential photometry and point spread function (PSF) photometry, to determine which will provide the greatest photometric precision. I will present the light curves and a comparison of the photometric precision achieved using the three different reduction schemes.
