We present preliminary results obtained from the photometric study of four galactic open clusters (OCs) with little known characteristics. The observations were made with the and filters of the Washington photometric system, using the 0.9 m telescope of the Cerro Tololo Inter-American Observatory (Chile). The results include the determination of some astrophysical parameters of the studied clusters and represent the continuation of a systematic study that is being carried out at the Astronomical Observatory of Córdoba. This study is part of a larger project that aims at characterising almost one hundred galactic OCs observed in the Washington system, which are being analysed in a similar way. In some cases, discrepancies are found between the present results and those inferred from photometric data obtained in the near-infrared spectral region.
