Scientific paper

UBV, DDO and Washington photometry for 14 red giant candidates of the open cluster NGC 2447 is presented. Membership results emerging from the application of two photometric criteria are in excellent agreement with those derived from published Coravel radial velocities. A mean cluster reddening E(B-V) = 0.05 +/- 0.04 is derived. Both the ultraviolet excesses and cyanogen anomalies of the cluster giants imply [Fe/H] ≃ -0.1. Five Washington abundance indicators yield a mean cluster metallicity of [Fe/H]_W = -0.09 +/- 0.06.
