Galactic evolution is studied in a field in the centre of the Large Magellanic cloud (LMC) Bar. We obtain data of high quality with the Hubble Space Telescope (HST) Wide Field and Planetary Camera 2 (WFPC2) and uvby photometry. To match the photometric accuracy and make use of the potential of the uvby system in terms of evolutionary parameters and chemical abundance, we need adequate calibration of the data observed. Conversion of the observing system into that of the international uvby system is made from observations of reference stars in cluster fields. These fields are first observed with a ground based telescope together with selected sets of standard stars for the uvby system. This way, the cluster field reference stars are tied into the international uvby system. Subsequently, the reference stars are observed with the HST WFPC2 used with its set of uvby filters, thus providing final system conversion. We here discuss the observations and present some initial results.
