We present results from an on-going study of stellar populations in the Local Group Galaxy M33. By comparing the multi-band photometry to model colors, we derive effective temperature and luminosity of the stellar objects, and information on the extinction by dust, in 27 fields sampling different environments across the galaxy. Two methods are used and the results compared. The stellar physical parameters are used to characterize the stellar populations in the observed fields which include several OB associations. We also reveal several massive star candidates.
