We present preliminary results obtained from a photometric analysis in the Washington system C and T_{1} passbands of two poorly known open clusters (OCs) located in the fourth Galactic quadrant: BH 84 and BH 211. Based on the best fits of theoretical isochrones to the (T_1,C-T_1) colour- magnitude diagrams, we derive the fundamental cluster parameters. The present results are part of a major project which aims to characterize almost a hundred OCs observed and analyzed in a homogeneous way.
