Intermediate-band, RI, and H-beta observations of the cluster NGC 2447 in Puppis, which contains nine or ten red giants and bright giants, are presented. Results are presented for 36 cluster stars. Photometric parameters are also presented for A and F type stars in the cluster, highly evolved A and F type stars, bright giants, normal red giants, red giants of Hyades abundances, and O type stars. The reddening and luminosities of the normal cluster giants are exhibited, and the relation between R-I and b-y for O type stars is shown. The luminosity and reddening calibrations for A/F stars and red normal giants and bright giants give concordant results.
